Why are 1,4 adducts of 1, 3-butadiene are more stable than 1, 2-adduet?

Explanation

To understand why 1,4-adducts of 1,3-butadiene are more stable than 1,2-adducts, we can break down the explanation into a series of steps:

### Step 1: Structure of 1,3-Butadiene
1,3-butadiene has the following structure:
- H2C=CH-CH=CH2

### Step 2: Formation of Adducts
When 1,3-butadiene reacts with a reagent (like H2 or a halogen), two types of adducts can form:
