Problem: Which statement is always true according to VSEPR theory?a) The shape of a molecule is determined only by the repulsions among bonding electron groups.b) The shape of a molecule is determined by the repulsions among all electron groups.c) The shape of a molecule is determined only by the repulsions among nonbonding electron groups.d) The shape of a molecule is determined by the polarity of its bonds.

FREE Expert Solution

Valence shell electron pair repulsion (VSEPR) theory is a model for predicting the overall shape of a molecule. VSEPR theory postulates that a given molecule will adopt an ideal shape to reduce the repulsion between the surrounding elements and the lone pairs on the central element.
