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. Where X- = -Cl - O-overset(O)overset(||)C-R-OR, -NR(R) etc. Why aldeydes and Ketones give nucleophilic addition reaction while acid derivatives prefer nucleophilic acyl substititution reaction?
