The rate of nucleophilic attack on compound is determined by the stability of the compound. More is the stability of a compound; less is the
(b)
Interpretation:
The order of given compounds in increasing rate of nucleophilic attack at
Concept introduction:
The rate of nucleophilic attack on compound is determined by the stability of the compound. More is the stability of a compound; less is the rate of the reaction. The stability of compound depends upon the number of resonating structures. More the resonating structures of compound more will its stability.
