NEET Chemistry VSEPR Theory MCQ Question
For a molecule with the formula AB2E2, where A is the central atom, based on VSEPR theory, what is the approximate bond angle between the A-B bonds?
104.5°
107.0°
109.5°
120.0°
Correct Answer
Detailed Explanation
In VSEPR theory, a molecule with the formula AB2E2 has a bent shape due to the presence of two lone pairs, resulting in a bond angle of approximately 104.5°, which is less than the tetrahedral angle of 109.5° due to lone pair-bond pair repulsions.
