How will you convert ethnal into the following compounds ?
i. Butane-1,3-idol , ii. But-2-enal
iii. But-2-enoic acid

Explanation

To convert ethanol (CH3CHO) into the specified compounds, we will follow a series of chemical reactions. Let's break down the conversions step by step.

### i. Conversion of Ethanol to Butane-1,3-diol

1. **Starting Material**: Ethanol (CH3CHO).
2. **Aldol Condensation**: Treat ethanol with dilute NaOH. This will lead to aldol condensation, resulting in the formation of 3-hydroxybutanal (CH3CH(OH)CH2CHO).
