Write the structures of compounds A,B and C in the following reactions:
(a) `CH_(3)-COOHoverset(NH_(3)//Delta)toAoverset(Br_(2)//KOH(aq))toBoverset(CHCl_(3)+alc.KOH)toC`

Explanation

To solve the given problem, we need to identify the structures of compounds A, B, and C based on the reactions described. Let's break it down step by step.

### Step 1: Identify Compound A
1. **Starting Compound**: The reaction begins with acetic acid (CH₃COOH).
2. **Reaction with Ammonia**: When acetic acid reacts with ammonia (NH₃) under heating (Δ), it forms an ammonium salt.
- The reaction can be represented as:
\[
CH₃COOH + NH₃ \rightarrow CH₃COONH₄
