Allyl chloride is more reactive than n-propyl chloride towards unimolecular nucleophilic substitution reaction. Explain why ?

Explanation

To explain why allyl chloride is more reactive than n-propyl chloride towards unimolecular nucleophilic substitution reactions (SN1), we need to analyze the stability of the carbocations formed during the reaction.

### Step-by-Step Solution:

1. **Understanding the Structures**:
- Allyl chloride (C3H5Cl) has the structure CH2=CH-CH2-Cl.
- n-Propyl chloride (C3H7Cl) has the structure CH3-CH2-CH2-Cl.
