Condider the following substances
`{:(i.HCHO, ii.CH_(3)CHO),(iii. CH_(3)CH_(2)COCH_(3),iv.CH_(3)CH_(2)COCH_(2)CH_(3)):}`
The correct order of reactivity towaards nucleophilic addition reaction is

A

`igt iigt iiigt iv`

B

`igtiigtivgtii`

C

`igtivgtiigtiii`

D

`igtiiigtiigtiv`

Text Solution

Verified by Experts

The correct Answer is:
A
Aldehydes are more reactive towards nucleophilic addition reaction. If group or atom shows positive inductive effect then it decreases the reactivity of carbonyl compound.
So, sequence of reactivity is
` HCHO gt CH _ 3 CHO gt CH _ 3 CH _ 2 COOCH _ 3 gt CH _ 3 CH _ 2 COCH _ 2CH _ 3 `
