Biomolecules Question 142
Question: Which compound can exist in a dipolar (zwitter ion) state
[Pb. PMT 1998]
Options:
A) $ C_6H_5CH_2CH(N=CH_2)COOH $
B) $ {{(CH_3)}_2}CH.CH(NH_2)COOH $
C) $ C_6H_5CONHCH_2COOH $
D) $ HOOC.CH_2CH_2COCOOH $
Show Answer
Answer:
Correct Answer: B
Solution:
$ {{(CH_3)}_2}.CH.\underset{NH_2}{\mathop{\underset{|}{\mathop{CH}}}}-COOH $ ⇌ $ {{(CH_3)}_2}-CH.\underset{NH_3^{+}}{\mathop{\underset{|}{\mathop{CH-CO{O^{-}}}}}} $
