Which of the following is the correct order of increase in repulsion of electron pair groups?
A. lone pair to lone pair lone pair to bond pair bond pair to bond pair B. bond pair to bond pair, lone pair to lone pair, lone pair to bond pair C. bond pair to bond pair, lone pair to bond pair, lone pair to lone pair D. lone pair to bond pair, lone pair to lone pair, bond pair to bond pair
Correct Answer: C
Explanation
According to Valence Shell Electron Pair Repulsion (VSEPR) theory, there is repulsion between electron pairs. The greatest of such repulsions is the one between a lone pair and another lone pair of electrons, followed by that between a lone pair and a bond pair and lastly that between a bond pair of electrons and another bond pair of electrons
