Presict the shapes of the following molecules on the basis of hybridisation.
`BCl_(3),CH_(4),CO_(2),NH_(3)`

Explanation

To predict the shapes of the molecules BCl₃, CH₄, CO₂, and NH₃ based on hybridization, we can follow these steps:

### Step 1: Determine the Hybridization of BCl₃
1. **Identify the central atom**: Boron (B).
2. **Count the valence electrons**: Boron has 3 valence electrons.
3. **Count the number of surrounding atoms**: There are 3 chlorine (Cl) atoms.
4. **Use the hybridization formula**:
\[
