Question

When ethanal and propanal are heated in presence of dilute $NaOH$, then the possible product(s) formed in the reaction is/are

• A. $2-$Methylbut$-2-$enal
• B. $2-$Methylpent$-2-$enal
• C. Pent$-2-$enal
• D. All of the above

Answer 1

The correct option is D All of the above

When ethanal and propanal are heated in presence of dilute $NaOH$, then aldol condensation takes place.
Here the simple or self aldol condensation takes place to give but$-2-$enal and $2-$methylpent$-2-$enal whereas cross aldol condensation takes place to give pent$-2-$enal and $2-$methylbut$-2-$enal.
