Question

Assertion : Aldol condensation can be catalysed can be cataysed both acid and bases.
Reason : `beta`- hydroxy aldehydes or ketones readily undergo acid catalysed dehydration.
A. If Both assertion and reason are true reason is a true explation of the assertion.
B. If Both assertion and reason are true but the reason is not the correct explation of the assertion.
C. If assertion is true but reason is false.
D. If assertion is false but reason is true.

Answer 1

Correct Answer - B
Both carbonions (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 aldhydes and ketons to give aldols.
