The correct order of their reactivity towards hydrolysis at room temperature is:

Options

  1. A( A ) > ( B ) > ( C ) > ( D )
  2. B( D ) > ( A ) > ( B ) > ( C )
  3. C( D ) > ( B ) > ( A ) > ( C )
  4. D( A ) > ( C ) > ( B ) > ( D )

Correct answer

A. ( A ) > ( B ) > ( C ) > ( D )

Step-by-step solution

+ M group attached with carbonyl bond will decrease reactivity of acid derivative towards hydrolysis. For halogen - I dominate over + M therefore, acid chloride is most reactive. As extent of + M effect increases, reactivity decreases. Overall, order of reactivity is:
