The product obtained from the catalytic reduction of propanal is:

Propan-1-ol

The correct answer is option 1. Propan-1-ol.

The simplest large-scale procedure for reduction of aldehydes and ketones to alcohols is by catalytic hydrogenation. Catalytic hydrogenation is simultaneously an addition reaction (addition of \(H_2\)) and a reduction (gain of hydrogen). The product is an alcohol. Aldehydes produce primary alcohols, while ketones produce secondary alcohols. Tertiary alcohols cannot be obtained from aldehydes and ketones. This reaction is the opposite of oxidation.
