Give the structures of the following :
( i) Phenyl acetic acid (ii ) Trimethyl acetic acid (iii ) Iso - valeric acid (iv ) Malonic acid
(v ) Adiopic acid

Explanation

To provide a clear solution for the structures of the specified acids, let's go through each of them step by step.

### Step 1: Phenylacetic Acid
1. **Identify the components**: Phenylacetic acid consists of an acetic acid part (which has two carbon atoms) and a phenyl group (which is a benzene ring).
2. **Draw the structure**:
- Start with the acetic acid: CH₃-COOH (which is CH₃-CO-).
- Attach the phenyl group (C₆H₅) to the carbon adjacent to the carboxylic acid group.
- The final structure is:
...
