Aldehyde and ketone having α-hydrogen atom undergo aldol condensation in presence of dilute base to give β -hydroxy aldehydes or ketones Acetone has α-hydrogen atom, hence it will give aldol condensation reaction <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/3e914583b3eb9a934438950b0a81aa27-.png" />

Q. Which of the following, is an example of aldol condensation?

$2 C H_{3} COC H_{3} dil NaOH C H_{3} CO H C H_{3} C H_{2} COC H_{3}$

$2 H C H O dil NaOH C H_{3} O H$

$C_{6} H_{5} C H O + H C H O dil NaOH C_{6} H_{5} C H_{2} O H$

None of the above

Aldehyde and ketone having $α$ -hydrogen atom undergo aldol condensation in presence of dilute base to give $β$ -hydroxy aldehydes or ketones
Acetone has $α$ -hydrogen atom, hence it will give aldol condensation reaction
