Write the structures of
(i) N-methylethanamine and
(ii) 2-aminotoluene.

Explanation

To solve the question, we need to draw the structures of two organic compounds: N-methylethanamine and 2-aminotoluene. Let's break this down step by step.

### Step 1: Understanding N-methylethanamine
N-methylethanamine is an amine derived from ethanamine (also known as ethylamine) with a methyl group (–CH3) attached to the nitrogen atom.

1. **Start with the structure of ethanamine (ethylamine)**:
- Ethanol (C2H5) has the formula:
