Question

The angle between $s{p}^2$ hybrid orbitals is

• A. ${120}^o$
• B. ${90}^o$
• C. ${180}^o$

Answer 1

The correct option is A ${120}^o$

One s and two p orbitals combine to form three $s{p}^2$ hybrid orbitals. The three hybrid orbitals must be at the maximum distance from each other to avoid repulsions. This is only possible when they are at an angle of ${120}^o$ from each other.
Thus, $s{p}^2$ hybrid orbitals are at ${120}^o$ angle to each other.
