The correct bond angle for \(\mathrm{sp}^2\) hybridization is:
1. \(90^\circ\)
2. \(120^\circ\)
3. \(180^\circ\)
4. \(109^\circ\)

HINT: Trigonal planar geometry.
Explanation:
For sp2 hybridization, the geometry is generally trigonal planar.
What are some examples of trigonal sp^2 hybrids? | Socratic
Thus, the bond angle is 120°
