Which of the following angle corresponds to sp2 hybridisation?A 90° B 120° C 180° D 109°

The angle that corresponds to sp2 hybridization is 120°. So, the correct answer is B. 120°.

Here's a step-by-step explanation:

1. Hybridization is a concept in chemistry that explains the shape of molecules. It's based on the idea that atomic orbitals combine to form new hybrid orbitals.

2. In sp2 hybridization, one s orbital and two p orbitals in the same atom mix to form three equivalent orbitals.

3. Each of these new sp2 hybrid orbitals arranges themselves in a way to be as far apart as possible, which results in a trigonal planar geometry.

4. The angle between any two sp2 hybrid orbitals in a trigonal planar geometry is 120°.
