In the compound given below the correct order of the acidity of the position X, Y and Z isA. `ZgtXgtY`B. `XgtYgtZ`C. `XgtZgtY`D. `YgtXgtZ`

Answer» Correct Answer - B
(i) Position (X) is most acidic due to `-COOH` group.
`-NH_3^(+)` group at position Y is more acidic than at Z because of presence of electron withdrawing `-COOH` group in close proximity. Hence `-NH_3^(+)` group at position Z is least acidic.
