Based on VSEPR theory,which should have the smallest XAX bond angle?

Question

Quizplus · Accepted Answer

According to VSEPR theory, the XAX bond angle is determined by the number of electron pairs (both bonding and nonbonding) around the central atom. Choice C has only two electron pairs (two bonding pairs) around the central atom, which results in a linear geometry and a bond angle of 180 degrees, making it the smallest XAX bond angle. Choices A, B, and D have three electron pairs, resulting in a trigonal planar geometry and a bond angle of 120 degrees.
