Which of the following is an example of aldol condensation?

A

`2CH_(3)COCH_(3)overset("Dil. " NaOH) to(CH_(3))(2)OH)CH_(2)COCH_(3)`

B

`2HCHOoverset("Dil. " NaOH) toCH_(3)OH`

C

`C_(6)H_(5)CHO+HCHO overset(Di.NaOH) to C_(6)H_(5)CH_(2)OH`

D

None of above

Text Solution

Verified by Experts

The correct Answer is:
A
Aldehyde and ketone having `alpha`- hydrogen atom undergo aldol condensation in the presence of dilute base to give `beta`- hydroxy aldehydes or ketones.
Acetone has `alph`- hydrogen atom, hence it will give aldol condensation reaction.
