Q. Which of the following, is an example of aldol condensation?
UPSEE
UPSEE 2008
A
$ 2CH_{3}COCH_{3} \ce{ ->[dil \, NaOH] } CH_{3}COHCH_{3}CH_{2}COCH_{3} $
B
$ 2HCHO \ce{ ->[dil \, NaOH] } CH_{3}OH $
C
$ C_{6}H_{5}CHO+ HCHO \ce{ ->[dil \, NaOH] } C_{6}H_{5}CH_{2}OH $
D
None of the above
Solution:
Aldehyde and ketone having $\alpha$-hydrogen atom undergo aldol condensation in presence of dilute base to give $\beta$ -hydroxy aldehydes or ketones
Acetone has $\alpha$-hydrogen atom, hence it will give aldol condensation reaction
