In case aldehydes and ketones there is addition of nucleophile but in case of acyl compound there is nucleophile substitution. Explain.

Text Solution

Verified by Experts

The correct Answer is:
In case of carbonyl compounds `H^(-)` or `R^(-)` are poor leaving group, therefore addition take place But in case of acid derivatives, `Z^(-) are good leaving group therefore subsitution take palace.

Both carbonyl compounds and acid derivatives though they contain grouping yet the reactions given by them are entirely different. As Aldehydes and Ketones give addition product with a nucleophile, while carboxylic acid derivatives give nucleophilic acyl substitution through addition/elimination mechanism.
