Indicate the `sigma & pi` bonds in
(i) `CH_(2)Cl_(2)`
(ii) `CH_(3)-C-=C-CH_(3)`

Explanation

To solve the problem of indicating the sigma (σ) and pi (π) bonds in the given compounds, we will analyze each compound step by step.

### Step 1: Analyze CH₂Cl₂

1. **Draw the Lewis Structure**:
- The molecular formula CH₂Cl₂ indicates that there is one carbon (C) atom bonded to two hydrogen (H) atoms and two chlorine (Cl) atoms.
- The structure can be represented as:
```
