Give the structure and IUPAC name of an aliphatic aldehyde having five carbon atoms which undergoes Cannizzaro's reaction

Explanation

To solve the problem, we need to identify an aliphatic aldehyde with five carbon atoms that can undergo Cannizzaro's reaction. Here's the step-by-step solution:

### Step 1: Understand Cannizzaro's Reaction
Cannizzaro's reaction occurs with aldehydes that do not have alpha-hydrogens. This means we need to find an aldehyde that has no hydrogen atoms attached to the carbon adjacent to the carbonyl group (the carbon of the aldehyde).

### Step 2: Identify the Structure
We need to find an aliphatic aldehyde with five carbon atoms. The simplest way to achieve this is to consider the structure of pentanal, which is a straight-chain aldehyde with five carbons. However, pentanal has alpha-hydrogens.
