Epoxides of `alpha,beta`-unsaturated carbonyl compounds can be formed by peroxy acid as well as with `H_(2)O_(2)//O^(Θ)H`. Explain the formation of epoxides in both cases.

Explanation

To explain the formation of epoxides from α,β-unsaturated carbonyl compounds using peroxy acid and hydrogen peroxide (H₂O₂) in a basic medium, we can break down the processes into two distinct mechanisms.

### Step-by-Step Solution

#### Case 1: Formation of Epoxides using Peroxy Acid

1. **Starting Material**: Consider an α,β-unsaturated carbonyl compound, such as CH₂=CH-CHO (where CHO is the carbonyl group).
