    Does nitrogens lone pair take part in resonance? For example, if you have a 6 carboned diene with a nitrogen atom in the center (dipropenyl amine I think would be the name), does resonance occur? I know that in pyridine, the nitrogens double bond plays a role in the resonance structure but I dunno if this always occurs. The example I have in mind is creatine. Is the creatine molecule a conjugated system?

    @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.

    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.

    Doubt----One thing is strange of an electron... In the Carbonate(CO3^-2) from where the two single bonded oxygen atoms got single extra electrons? As oxygen have six electrons in its outer shell, it pairs covalently with carbon to fulfill the needed two, ..........but in the video its shown one atom is used in single bond with carbon and still oxygen is having 6 electrons on the side......(summing up 7 electrons with oxygen and a sigma bond)......so from where the oxygen took that one more electron??

    @Ray12able so perhaps what u r saying is dat carbon must form only 2 bonds???? bt it isnt dat way....the 2 electrons in a bond (single bond) do nt belong to just i element invlvd in the bond formation.....two elements contribute 1 electron each ....hence carbon contributes its 4 valence electrons in making a bond with 4 monovalent species(for single bonds)....and eventually after the bond is formed the shared pair of electrons then blong to both the corspndng elements....hope that helps...

    Charges are unfavorable. No compound wants to have a net charge on it. Because, the net charge attracts nucleophiles or electrophiles according to the net charge. *Do not mistake compounds with 'elements' like Sodium & Lithium which readily gets ionised and lose one electron and are found in such state in nature. Na+, Li+ etc.
