Arrange the different type of conformations of butane in the decreasing order of stability.

Explanation

To arrange the different types of conformations of butane in decreasing order of stability, we can follow these steps:

### Step 1: Understand the Conformations of Butane
Butane (C4H10) can adopt various conformations due to the rotation around its carbon-carbon single bonds. The main conformations are:
1. **Anti (Staggered)**
2. **Gauche (Skew)**
3. **Partially Eclipsed**
4. **Fully Eclipsed**
