Ethanal is soluble in water. Why?

Explanation

### Step-by-Step Solution:

1. **Understanding Ethanol**: Ethanol, also known as acetaldehyde, has the molecular formula \( C_2H_6O \) or structurally represented as \( CH_3CHO \). The molecule consists of a two-carbon chain with a carbonyl group (C=O) and a hydroxyl group (–OH).

2. **Structure of Ethanol**: The structural formula of ethanol can be depicted as:
\[ H_3C - C(=O) - H \]
