A) \[{{C}_{6}}{{H}_{5}}C{{H}_{2}}CH(N=C{{H}_{2}})COOH\]
B) \[{{(C{{H}_{3}})}_{2}}CH.CH(N{{H}_{2}})COOH\]
C) \[{{C}_{6}}{{H}_{5}}CONHC{{H}_{2}}COOH\]
D) \[HOOC.C{{H}_{2}}C{{H}_{2}}COCOOH\]
Correct Answer: B
Solution :
\[{{(C{{H}_{3}})}_{2}}.\,CH.\underset{N{{H}_{2}}}{\mathop{\underset{|\,\,\,\,\,\,\,\,}{\mathop{CH\,\,}}\,}}\,-COOH\] ⇌ \[{{(C{{H}_{3}})}_{2}}-CH.\underset{N{{H}_{3}}^{+}\,\,\,\,\,\,\,\,\,\,\,\,}{\mathop{\underset{|\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,}{\mathop{CH-CO{{O}^{-}}}}\,}}\,\]
