Reactivity  towards  nucleophilic  addition reaction of (I) HCHO (II)\[C{{H}_{3}}CHO\](III) \[C{{H}_{3}}COC{{H}_{3}}\]is

A)  \[II>III>I\]       

B)  \[III>II>I\]

C)  \[I>II>III\]        

D)  \[I>II<III\]

Correct Answer: C

Solution :

 Aldehydes and ketones readily undergo nucleophilic addition reaction. The reactivity decreases as the \[+I\] effect of alkyl group increases.
