The equilateral shape has

Options

A. sp hybridisation
B. `sp^2` hybridisation
C. `sp^3` hybridsation
D. `dsp^2` hybridisation

Explanation

To solve the question regarding the hybridization associated with an equilateral shape, we will follow these steps:

### Step-by-Step Solution:

1. **Understanding the Shape**:
- The term "equilateral shape" typically refers to a geometric arrangement where all sides and angles are equal. In chemistry, this is often associated with a trigonal planar arrangement.

2. **Identifying the Hybridization**:
- The trigonal planar shape corresponds to a hybridization state. For a trigonal planar geometry, the hybridization is **sp²**. This is because one s orbital mixes with two p orbitals to form three equivalent sp² hybrid orbitals.

3. **Drawing the Hybridization**:
- To visualize sp² hybridization, we can draw:
- One s orbital and two p orbitals.
- These orbitals combine to form three sp² hybrid orbitals arranged in a plane at 120° angles to each other.

4. **Example of sp² Hybridization**:
- A common example of a molecule with sp² hybridization is **BF₃ (Boron Trifluoride)**.
- In BF₃, the boron atom is at the center, and the three fluorine atoms are positioned at the corners of an equilateral triangle, maintaining 120° bond angles.

5. **Conclusion**:
- Therefore, the correct hybridization for an equilateral shape (trigonal planar) is **sp²**.

### Final Answer:
The equilateral shape has **sp² hybridization**.
