Shape of a molecule having four bond pairs and two lone pairs of electrons will be

Options

A. square plannar
B. Tetrahedral
C. Linear
D. octahedral

Answer

To determine the shape of a molecule with four bond pairs and two lone pairs of electrons, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Number of Bond Pairs and Lone Pairs:**
- The molecule has 4 bond pairs and 2 lone pairs of electrons.

2. **Determine the Total Number of Electron Pairs:**
- Total electron pairs = Bond pairs + Lone pairs = 4 + 2 = 6 electron pairs.

3. **Determine the Hybridization:**
- The hybridization can be determined based on the total number of electron pairs. For 6 electron pairs, the hybridization is sp³d².

4. **Identify the Molecular Geometry:**
- The electron pair geometry for sp³d² hybridization is octahedral. However, we need to consider the positions of the lone pairs.

5. **Positioning of Lone Pairs:**
- In an octahedral arrangement, the lone pairs will occupy positions that minimize repulsion. Typically, lone pairs will occupy axial positions in an octahedral geometry.

6. **Determine the Shape of the Molecule:**
- With 4 bond pairs in the equatorial plane and 2 lone pairs occupying the axial positions, the shape of the molecule is square planar. This is because we only consider the positions of the atoms (bond pairs) when describing the shape, not the lone pairs.

### Final Answer:
The shape of the molecule having 4 bond pairs and 2 lone pairs of electrons is **Square Planar**.
