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

Options

A $( A ) > ( B ) > ( C ) > ( D )$
B $( D ) > ( A ) > ( B ) > ( C )$
C $( D ) > ( B ) > ( A ) > ( C )$
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: The correct order of their reactivity towards hydrolysis at room temperature is:

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