NEET Chemistry VSEPR Theory MCQ Question
According to VSEPR theory, which of the following geometries is expected for a molecule with the formula AB3E, where E represents a lone pair?
Trigonal pyramidal
Tetrahedral
Bent or V-shaped
Linear
Correct Answer
Detailed Explanation
The presence of one lone pair (E) in AB3E results in trigonal pyramidal geometry due to lone pair-bond pair repulsion reducing bond angles from the ideal tetrahedral geometry.
