Out of `(CH_(3))_(3)C-Br and (CH_(3))_(3)C-I`, which one is more reactive towards `S_(N)l` and why?

Explanation

To determine which compound, (CH₃)₃C-Br or (CH₃)₃C-I, is more reactive towards the SN1 reaction, we need to analyze the factors that influence the reactivity in SN1 mechanisms.

### Step-by-Step Solution:

1. **Understanding SN1 Mechanism**:
- The SN1 reaction involves two main steps:
1. Formation of a carbocation (rate-determining step).
2. Nucleophilic attack on the carbocation.
