Assertion: Acetaldehyde on treatment with alkali gives aldol.
Reason: Acetaldehyde molecules contains `alpha` hydrogen atom.

A

If both assertion and reason are true and the reason is the correct explanation of the assertion.

B

If both assertion and reason are true but reason is not the correct explanation of the assertion.

C

If assertion is true but reason is false.

D

If the assertion and reason both are false.

Text Solution

Verified by Experts

The correct Answer is:
A
Carbonyl compounds having α-hydrogen atom condenses to produce aldol in presence of alkali.
`underset("Acetaldehyde")(CH_3-underset(O)underset(||)(CH)+HCH_2CHO) overset("dil. NaOH")to underset("Aldol")(CH_3-underset(OH)underset(|)(CH)-CH_2CHO)`
