Options

  1. Ait does not exist as Zwitter ion
  2. B−NH2- {NH}_{2}& group displays a powerful basic character
  3. Cit does not act as inner salt
  4. D−SO3H- {SO}_{3}H, diminishes the basic character of −NH2- {NH}_{2}

Correct answer

D. −SO3H- {SO}_{3}H, diminishes the basic character of −NH2- {NH}_{2}

Step-by-step solution

For the reaction C _ 6 H _ 5 . NH _ 2 → _ 180 ° C ^ H _ 2 SO _ 4 H _ 2 N · C _ 6 H _ 4 ( SO _ 3 H) _ Para & the true

A zwitterion is a compound with no overall electrical charge, but which contains separate parts which are positively and negatively charged.

Sulphanilic acid exist as dipolar ion (zwitter ion); act as inner salt and SO3H{SO}_{3}H group diminishes the basic character of −NH2- {NH}_{2}.
