which of the following cation would have greatest stability?
The correct option is b
This is because the stability is maximised by back bonding, also known as - back bonding. This takes place between nitrogen and carbon atoms. During this phenomenon, the electron density is shifted (donated) to the empty * orbital. Therefore, the electrons from nitrogen will shift to the single bond between nitrogen and carbon and form a double bond.
The major products obtained from the reactions in List-II are the reactants for the named reactions mentioned in List-I. Match each entry in List-I with the appropriate entry in List-II and choose the correct option.
