Complete the following by suppling intermediates
`CH_(3)Br overset(Na)underset(ether)(to)A overset(Br_(2))underset(hv)(to)B overset(Na)underset(ether)(to) C`

Explanation

To solve the given question, we need to identify the intermediates formed during the reactions of methyl bromide (CH₃Br) with sodium in ether, followed by bromination with Br₂ under UV light, and then another reaction with sodium in ether. Let's break it down step by step.

### Step-by-Step Solution:

1. **Starting Material: CH₃Br**
- We start with methyl bromide (CH₃Br), which is an alkyl halide.

2. **First Reaction: CH₃Br + Na (in ether) → A**
