The acidic strength of active methylene ...

The acidic strength of active methylene group in
I. `CH_(3)COCH_(2)COOH_(2)H_(5)`
II.`CH_(3)COCH_(2)COOH_(3)`
III. `C_(2)H_(5)OOC CH_(2)COOC_(2)H_(5)`

A

`I gt III gt II`

B

`I gt II gt III`

C

`II gt I gt III`

D

`III gt I gt II`

Text Solution

Verified by Experts

The correct Answer is:
C
Acidic strength in active methylene compounds can be decided by two factors
(i) Presence of electron withdrawing group.
(ii) Stability of enolate anion obtained after removal of `H^(+)`
Hence, `II gt I gt III`
