`CH_(3)CHO` is more reactive than `CH_3COCH_3` towards reaction with HCN. Give reason.

Explanation

To understand why CH₃CHO (acetaldehyde) is more reactive than CH₃COCH₃ (acetone) towards reaction with HCN (hydrogen cyanide), we need to analyze the structures and the electronic effects present in these compounds.

### Step-by-Step Solution:

1. **Identify the Structures**:
- CH₃CHO is acetaldehyde, which has the structure:
