Aldehyde, ketone, carboxylic acid derivatives contain C= O group. Aldehyde and ketones give nucleophilic addition reactions where as acid and acid derivatives give nucleophilic addition followed by elimination reactions. Nucleophilic addition reactions followed by elimination of acid dervatives is Known sacyl substitution reaction. This substitution reaction takes place by formation of tetrahedral intermediate. For the given reaction
which of these is correct ?
A. L must be better leaving group than Nu
B. `Nu^(-)` must be strong enough nucleophile to attack carbonyl carbon
C. Carbonyl carbon must be enough electrophilic to react with `Nu^(-)`
D. all of these
