Which of the following gives aldol condensation reaction?

A

`C_(6)H_(5)OH`

B

`C_(6)H_(5)-overset(O)overset(||)(C )-C_(6)H_(5)`

C

`CH_(3)CH_(2)-overset(O)overset(||)(C )-CH_(3)`

D

`(CH_(3))_(2)C-overset(O)overset(||)(C )-CH_(3)`

Text Solution

Verified by Experts

The correct Answer is:
C
Although both `CH_(3)CH_(2)COCH_(3)` and `(CH_(3))_(3)C COCH_(3)` contain `alpha`-hydrogen, yet `(CH_(3))_(3)C COCH_(3)` does not undergo Aldol condensation due to steric hindrance.
