Name the shapes of the following molecules : `CH_(4) , C_(2)H_(2)m CO_(2)`

Explanation

To determine the shapes of the molecules CH₄, C₂H₂, and CO₂, we will analyze each molecule step by step, considering their hybridization, bond pairs, and lone pairs.

### Step 1: Analyze CH₄ (Methane)
1. **Determine Hybridization**:
- In CH₄, the carbon atom forms four single bonds with hydrogen atoms.
- The hybridization of carbon in CH₄ is sp³.

2. **Count Bond Pairs and Lone Pairs**:
