Tellurium Chemistry: Aromatic Polycation Te4(2+)
 
02:00
Much like our experiment with Selenium, Tellurium forms polycations in conc. H2SO4 as well. In this case, the color is red. Back then we had an 8-membered crown-shaped ring. Tellurium, however, forms a different polycation under the same conditions. This time a square is formed which consists of 4 Tellurium atoms. As the system contains 6 pi-electrons* and it is flat we call this a Hueckel aromatic compound. Besides Te4(2+), S4(2+) and Se4(2+) can form under different conditions as well and those are aromatic, too. Why does this compound form so fast in comparison to a sulfur polycation which requires Oleum to form ? Sulfur is much more electronegative and the cation possesses a much higher acidity. Thus, Tellurium is easier to react it in H2SO4 and no more reactive reagent is required. There are multiple ways to make the Te4(2+) and depending on the method and counterion it can further polymerize forming Te8(4+) as dimer, or [Te4(2+)]x as polymeric chain where the Te-squares are connected via the vertices. Note: * If you are unsure how to determine the amount of electrons here, this is the official calculation to this problem: - Number of valence electrons = 4 x 6 = 24 from this some electrons have to be subtracted - Number of sigma-electrons = 8 - Amount of lone pairs 2 x 4 = 8 - Charge = 2 If you subtract these 18 from 24 you get 6 pi-electrons in the system. Next to determine aromaticity you can use the Frost-Musulin-diagram. Take the shape of your ring and place it on a vertex. Each vertex is now an energy level. If you take benzene for example you will see that there are two times two vertices on the same height. Those are degenerate energy levels. Each of these "layers" have to be either completely empty or fully filled to yield a stable compound. Unpaired situations will lead to reactive radicals, which is why there are aromatic, anti-aromatic and non-aromatic compounds and the Hueckel-rules exist. Ok so we take our square and place it on an edge we get 4 energy levels (where each vertex is). Two of those will be at the same hight and therefore be degenerate. Now we know that we have 6 pi-electrons and each energy level can be filled with two electrons. This will fill the first and the second degenerate "layer" which is a stable situation making it aromatic. It is also flat, which is a requirement for aromatic compounds as well.

Hydrogen Bonding and Common Mistakes
 
09:00
To see all my Chemistry videos, check out http://socratic.org/chemistry Hydrogen bonding can be so confusing, and in this video we talk about some common mistakes. Hydrogen bonds are intermolecular forces between molecules. They form because one atom has a high electronegativity, so it gets a partial negative charge, and the hydrogen gets a partial positive charge.

Hybridisation of Carbon in Organic Compounds
 
10:26
In this video we want to discuss the concept of excitation and hybridisation of Carbon in Organic Compounds. We can use hybridisation to explain the shape of organic molecules with respect to carbon. 1. Methane, CH4 Let's consider carbon in methane, CH4. We know that the shape with respect to carbon is tetrahedral according to Valence Shell Electron Pair Repulsion Theory (VSEPR). Let's try to explain the shape via the electronic configuration of carbon instead. Carbon in the ground state has the following electronic configuration: 1s2 2s2 2p2. Carbon has only 2 unpaired electrons in this case, so therefore it can only form 2 bonds in its ground state. Of course we know that carbon always forms 4 bonds, so the concept of excitation comes in where an electron is promoted from the paired 2s orbital which is lower in energy to an empty 2p orbital which is higher in energy. Carbon in its excited state now has 4 unpaired electrons so can form 4 bonds. However, if carbon just uses these 2s and 2p orbitals for bond formation, the shape with respect to carbon will not be tetrahedral since 2s orbital is more stable and closer to the nucleus so bond formed will be shorter, while 2p orbital is less stable and further away from the nucleus so bond formed will be longer. This means we will have one shorter C-H bond (from 2s orbital) and 3 longer C-H bonds (from the 2p orbitals), which is hardly the highly symmetrical tetrahedral shape that we see in methane. Therefore we need another concept to connect between excitation and the final shape of methane - hybridisation. Hybridisation is the mixing of valence orbitals to form sigma bonds. Since carbon in methane forms 4 sigma bonds, it will mix 4 of its valence orbitals (2s, 2px, 2py, 2pz) to form 4 identical orbitals with equal shape and energy. The name of the hybridised orbitals will be sp3 hybridised orbitals and since they have the same shape and energy, they repel each other equally and give sp3 hybridised carbon in CH4 its highly symmetrical tetrahedral shape. 2. Ethene, C2H4 Carbon in ethene forms 3 sigma bonds and 1 pi bond. Since carbon forms 3 sigma bonds, it will mix 3 of its valence orbitals (2s, 2px, 2py) to form 3 identical orbitals with equal shape and energy. The name of the hybridised orbitals will be sp2 hybridised orbitals and since they have the same shape and energy, they repel each other equally and give sp2 hybridised carbon in C2H4 its trigonal planar shape. Remainder 2pz orbital is unhybridised and is used in pi bond formation. 3. Ethyne, C2H2 Carbon in ethyne forms 2 sigma bonds and 2 pi bonds. Since carbon forms 2 sigma bonds, it will mix 2 of its valence orbitals (2s, 2px) to form 2 identical orbitals with equal shape and energy. The name of the hybridised orbitals will be sp hybridised orbitals and since they have the same shape and energy, they repel each other equally and give sp hybridised carbon in C2H2 its linear shape. Remainder 2py and 2pz orbitals are unhybridised and used in pi bond formation. 4. Summary for State of Hybridisation for Carbon The following table will summarise what we need to know for hybridisation. Based on the number of sigma bonds that carbon forms, we can determine its state of hybridisation.

cis/trans nomenclature is effective only when the alkene has two different groups on each carbon atom of the double bond and each carbon has one of the same group. We saw that cis and trans fails in rings when the two carbons lacked a common substituent. It also fails for alkenes under these circumstances. (detailed explained inside the lecture). Thankfully, we can apply the ranking system developed by Cahn, Ingold, and Prelog for chiral centers for this purpose. The protocol is as follows: Each carbon in the pi bond is attached to two substituents. For each carbon, these two substituents are ranked (1 or 2) according to the atomic numbers of the atom directly attached to the carbon. (e.g. Cl greater F ) If both substituents ranked 1 are on the same side of the pi bond, the bond is given the descriptor Z (short for German Zusammen, which means “together”). If both substituents ranked 1 are on the opposite side of the pi bond, the bond is given the descriptor E (short for German Entgegen, which means “opposite”). So Z resembles “cis” and E resembles “trans”. (Note: they are not necessarily the same and do not always correlate:)The E/Zsystem is comprehensive for all alkenes capable of geometric isomerism, including the cis/trans alkene examples above. We often use cis/trans for convenience, but E/Z is the “official”, IUPAC approved a way to name alkene stereoisomers]. One easy way to remember Z is to say “Zee Zame Zide” in a German accent. My way of doing it was pretending that the Z stands for “zis”. Whatever works for you. An Important Bottom Line: cis-trans- is OK for describing simple alkene stereoisomers, but only works in certain cases. Furthermore, it only gives relative configurations. The E/Z system is comprehensive and describes the absolute configuration of the molecule. See below for an example of an E alkene which is “cis” and a Z alkene which is “trans”. Watch the lecture and understand Geometrical Isomerism in details with full confidence. We hope you will enjoy it.

Four easy methods to calculate Hybridization ( Important of NEET & JEE )
 
15:42
Hello friends this is SURYA DEV CHATURVEDI . Well Come To IITians Education. Hybridization is very important topic for JEE & NEET. There are many students which have difficulty to find hybridization so, I explain four different methods to find hybridization easily . Hybridization : It is the mixing of two or more atomic orbitals of almost same energy and the formation of same number of new orbitals of same energy & same share called Hybrid orbitals and the phenomena is called Hybridization. Important Features Of Hybridization 1)The number of hybrid orbitals is equal to the number of atomic orbitals that get hybridized. 2)The hybridized orbitals are always same in energy & shape. 3)The hybrid orbitals are more effective in forming stable bonds than the pure atomic orbitals. 4)These hybrid orbitals are directed in a shape in some preferred direction to have minimum repulsion between electron pairs and also gives geometry to the molecules. FORMULA OF HYBRIDIZATION - X = S.A + 1/2 ( E – V ± C) S.A.= Surrounding atoms. E = No. of electrons present in valence shell of a central atom V = Valency of surrounding atom. C = Opposite charge. other method HYBRIDIZATION = sigma bonds + lone pairs If You Like The Video Then Like It And Share It With Your Friends & Not Forget To Subscribe our Channel.

C6H6 Lewis Structure: How to Draw the Lewis Structure for C6H6 (Benzene)
 
02:22
A step-by-step explanation of how to draw the C6H6 Lewis Dot Structure (Benzene). There are several ways to draw the C6H6 Lewis structure. The most common is to form a ring with the six carbon atoms. You'll notice that there are not many hydrogen atoms in the structure. You'll need to form alternating double bonds in order to fill the outer shells of the atoms and only use 30 valence electrons. There are two other (probably more than that) ways to draw the Lewis structure for C6H6. These are equally valid structures and obey the octet rule while using only 30 valence electrons. For the C6H6 Lewis structure, calculate the total number of valence electrons for the C6H6 molecule (C6H6 has 30 valence electrons). After determining how many valence electrons there are in C6H6, place them around the central atom to complete the octets. Be sure to use the number of available valence electrons you found earlier.
