i had two midterms... for Orgo part one- i got 90 on my first midterm and and 79 on the second one. It honestly suprised me because i was very weak in my first year chem classes. anyways it's all thanks to the khanacademy instructor, a bit of motivation and LOTS of practice, and i mean LOTS. and if you are wondering i did donate my money (i had a job at the time) to a local charity here in Toronto (covenant house)-about $1000

[@russelljohnson2733]

notice how he made sure to use a subtle color to demonstrate the hydrogen bonds... that alone tells u how much work he puts into the videos he makes for us... legend

at my school they teach that a double headed arrow means the movement of and electron pair and a single headed arrow means the movement of a single electron. so it may differ but there has to be a way to distinguish between the movement of a single electron and a pair of electrons

Thank you for ur awesome videos you are super awesome and your videos are very much help full!!!!!!!!!!!!!!!!!!!!!!!!!!!!

[@Mojo-hh8qg]

@Mona Pap The reason for the -2/3 instead of a -1/3 charge on each oxygen would be true IF, the molecule itself was neutral. In this case carbonite ion has a negative -2 charge, thus giving each oxygen the lowest charge of -2/3 to form a total charge of -2 (-2/3 * 3 = -2). Hope this helps if you have not gotten an answer already.

[@meghas.r4702]

[@sameerkandeel6454]

Sir, the best way to explain resonance in benzene, is through the valence bond theory to account for the resonating strs. This theory which insists on the fact that covalent bond is two electron bond. So, if we draw benzene with sigma bonds, and the six carbon atoms with their pz orbitals containing one electron each, we can get the two resonating strs. After that, the we can go to the molecular orbital theory, to describe the resonance, by unifying the six pz orbitals of carbon atoms into six molecular orbitals three of bonding contain the six pz electrons, two for each of them, and three unoccupied antibonding M. O. This is represented by benzene ring with a circle inside.

[@SR-em8wl]

Who said Resonance cannot be fun! So beautifully explained. Just a doubt, is Resonance a naturally ongoing process among certain compounds (just like how breathing is to living organisms)?

[@samajlo4336]

It is just a theoretical concept which explains the stability of compounds.

[@missymonalisa]

why would it be - 2/3 charge on each oxygen atom? why isn't is -1/3?

[@damnyes5667]

Thank you sooo much.

[@94amandeepsingh]

1 double bond is being shared at three places, hence (1/3) of a double bond. But there are two "-1" charges on two Oxygen (first Lewis diagram), hence (-2/3) charge being shared.

[@bhanumohank995]

@nightmare4eVerr1 1 bond is made up of 2 electrons.So 2 bonds=4 electrons and is already has 4 electrons so total=8.
