Question
Chapter 3, Problem 3.32P
Interpretation Introduction
Interpretation: The molecule with the smallest
Concept introduction: The bond angles are related to the stability and the repulsions. If the repulsions between the electron pairs are high, then to minimize these, the bond angles get altered.
