How is aminoethane obtained from ethanal ?

Explanation

To obtain aminoethane from ethanal, we can follow these steps:

### Step 1: Reduction of Ethanal
1. **Starting Material**: Ethanal (acetaldehyde), which has the structure CH3CHO.
2. **Reduction Reaction**: Ethanal is reduced using Lithium Aluminium Hydride (LiAlH4). This reagent is a strong reducing agent that converts the carbonyl group (C=O) in ethanal to a hydroxyl group (–OH), resulting in the formation of ethanol (CH3CH2OH).
- **Reaction**:
\[
\text{CH}_3\text{CHO} + \text{LiAlH}_4 \rightarrow \text{CH}_3\text{CH}_2\text{OH}
