Which of the following statements regarding VSEPR theory is correct?

Question

Quizplus · Accepted Answer

VSEPR theory is used to predict the shape of a molecule based on its Lewis structure and the repulsion between its electron pairs. This theory takes into account both bonding and nonbonding electron pairs. Therefore, option A is incorrect because tetrahedral is a molecular shape which has four atoms (not three) and no unshared pairs of electrons on the central atom. Option B is incorrect because nonbonding electron pairs do influence molecular shape. Option C is incorrect because the Lewis structure is required to predict the shape of a molecule using VSEPR theory. Option E is incorrect because the molecular shape called "bent" can have one or two pairs of unshared electrons on the central atom depending on the molecule.
