Arrange the following in the increasing order of acidic strength
`(I) H_(2)CO`
(II) `CH_(3)CHO`
(III) `C_(6)H_(5)CH_(2)CHO`
`(IV) CH_(3)-overset(O)overset(||)C-CH_(2)-overset(O)overset(||)C-CH_(3)`

A

`I lt II lt III lt IV`

B

`IV lt III lt II lt I`

C

`III lt IV lt II lt I`

D

`III lt IV lt I lt II`

Text Solution

Verified by Experts

The correct Answer is:
A
`IV` is most acidic as its conjugate base is resonance stabilised by two carbonyl groups, followed by `III` whose conjugate base is resonance stabilised by a carbonyl group and phenyl ring.
