A) \[{{(C{{H}_{3}})}_{2}}NH\]
B)
C)
D) All of these
Correct Answer: D
Solution :
[d] Carbonyl compounds containing at least one \[\alpha \]-hydrogen atom react with a Secondary amine to give enamine \[\underset{\text{Primary}\,\,\text{amines}\,\,\text{also}\,\,\text{form}\,\,\text{enamines}}{\mathop{>CH-\overset{|}{\mathop{C}}\,=O+HN<_{R}^{R}\xrightarrow[-{{H}_{2}}O]{{}}C=\overset{|}{\mathop{C}}\,-N<_{R}^{R}}}\,\] \[\underset{\text{enamine}}{\mathop{>CH-\overset{|}{\mathop{C}}\,=O+{{H}_{2}}N-R}}\,\xrightarrow{{}}>C=\overset{|}{\mathop{C}}\,-N<_{R}^{H}\rightleftharpoons \,\,>\underset{\text{imine}}{\mathop{CH-\overset{|}{\mathop{C}}\,=N-R}}\,\] In second case enamme - amine tautomerism is possible and equilibrium lies completely on the imine side.You need to login to perform this action.
