A) \[{{H}_{3}}N-C{{H}_{2}}-CO{{O}^{-}}\]
B) \[{{H}_{3}}N-C{{H}_{2}}-COOH\]
C) \[{{H}_{2}}N-C{{H}_{2}}-COOH\]
D) \[{{H}_{2}}N-C{{H}_{2}}-CO{{O}^{-}}\]
Correct Answer: B
Solution :
At\[pH=4\], an amphoteric Zwitter ion structure changes into cation when an acid is added to it. \[\underset{^{\oplus }N{{H}_{3}}}{\mathop{\underset{|}{\mathop{R}}\,}}\,-CH-CO{{O}^{-}}\xrightarrow{+{{H}^{+}}}\underset{^{\oplus }N{{H}_{3}}}{\mathop{\underset{|}{\mathop{R}}\,}}\,-CH-COOH\]You need to login to perform this action.
