Which of the following compounds will undergo aldol condensation, which the Cannizzaro reaction and which neither ? Write the structures of the expected products of aldol condensation and Cannizzaro reaction.
Benzaldehyde

Explanation

To solve the question regarding benzaldehyde and its reactions, we will analyze its ability to undergo aldol condensation and the Cannizzaro reaction.

### Step 1: Determine if Benzaldehyde can undergo Aldol Condensation
Aldol condensation requires the presence of alpha hydrogen atoms adjacent to the carbonyl group (C=O) of the aldehyde or ketone.

- **Benzaldehyde Structure**:
- Benzaldehyde (C6H5CHO) has a carbonyl group (C=O) but does not have any alpha hydrogen atoms because the carbon adjacent to the carbonyl is part of the aromatic ring.
