Q. Assertion : Aldol condensation can be catalysed both by acids and bases.
Reason : $\beta$-Hydroxy aldehydes or ketones readily undergo acid catalysed dehydration.

AIIMSAIIMS 2010Aldehydes Ketones and Carboxylic Acids

Solution:

Both carbanions (formed in presence of base) and enol form (formed in presence of an acid) act as nucleophiles and hence add on the carbonyl group of aldehydes and ketones to give aldols.
