Concept explainers
(a)
To draw: The important resonating structures of the given cation.
Interpretation: The important resonating structures of the given cation are to be drawn.
Concept introduction: Resonance is the process in which a molecule gets different structures to define its bonding within the molecule. Such molecules cannot be represented in single Lewis structures. Resonating structures of such molecules are called contributing structures. In the process of resonance, shifting of lone pairs occur with the bonds and other lone pairs. Positive and negative charges decide the high or low electron density areas.
Large conjugation of lone pairs, double bond, triple bond and charge on atoms enhances the resonance.
