`2C_(6)H_(5)CHO overset(NaOH) to C_(6)H_(5)CH_(2)OH + C_(6)H_(5)COONa`
The similar reaction can take place with which of the following aldehyde?

A

`CH_(3)CHO`

B

`CH_(3)CH_(2)CHO`

C

`(CH_(3))_(3)C CHO`

D

`(CH_(3))_(2)CH CHO`

Text Solution

Verified by Experts

The correct Answer is:
C
`2C_(6)H_(5)CHO overset(NaOH)rarr C_(6)H_(5)CH_(2)OH+C_(6)H_(5)COONa`.
This is a cannizzaro's reaction taking place in Aldehyde having no `alpha`-hydrogen present. In Aldehyde `(CH_(3))_(3)CHO` in which no `alpha`-hydrogen is present-this reaction can take place.
