Question: What is the main product when propanal is treated with excess hydrogen in the presence of a catalyst?

Options:

Correct Answer: Propan-1-ol

Solution:

Propanal is reduced to propan-1-ol when treated with excess hydrogen in the presence of a catalyst.

What is the main product when propanal is treated with excess hydrogen in the presence of a catalyst?

What is the main product when propanal is treated with excess hydrogen in the presence of a catalyst?

Step 1: Identify the starting compound, which is propanal. Propanal is an aldehyde with the formula C3H6O.
Step 2: Understand that when propanal is treated with hydrogen (H2), a reduction reaction occurs.
Step 3: Recognize that a catalyst is used to speed up the reaction. Common catalysts for hydrogenation include palladium (Pd) or platinum (Pt).
Step 4: Know that during the reduction process, the carbonyl group (C=O) in propanal is converted to a hydroxyl group (–OH).
Step 5: The product formed from this reaction is propan-1-ol, which is an alcohol with the formula C3H8O.
