Vedclass · Answer

(D) $HCN$ undergoes nucleophilic addition with all three carbonyl compounds via the same mechanism.$NH_2NH_2$ and $NH_2OH$ react with all three via nucleophilic addition followed by elimination of $H_2O$ (condensation reaction).$NH_3$ reacts differently with each of these carbonyl compounds:$i$. $6 HCHO + 4 NH_3 \rightarrow (CH_2)_6N_4 + 6 H_2O$ (Formation of urotropine).$ii$. $CH_3CHO + NH_3 \rightarrow CH_3CH(OH)NH_2$ (Formation of an unstable aldehyde-ammonia adduct).$iii$. $2 CH_3COCH_3 + NH_3 \rightarrow (CH_3)_2C(NH_2)CH_2COCH_3$ (Formation of diacetone amine via condensation).

Which of the following reagents reacts differently with $HCHO$,$CH_3CHO$,and $CH_3COCH_3$?
