AIIMS 2018 Chemistry Molecular Geometry MCQ Question
Type: MCQ-conceptual-Medium-Class 11
Correct order of bond angle is:
A
<
B
<
C
<
D
<
Correct Answer
Option D
Detailed Explanation
Option D is correct because the bond angles in the given compounds do not follow a consistent order due to the influence of lone pairs and molecular geometry. In SO₂, the bond angle is approximately 120° due to its bent shape, while H₂S has a bond angle of about 92°, making option A incorrect. Similarly, H₂O has a bond angle of about 104.5°, which is larger than that of NH₃ (approximately 107°), thus making option C incorrect as well. Understanding the effects of lone pairs on bond angles is crucial for predicting molecular geometry.
