According to the VSEPR model, a molecule with the general formula AB₅ with one lone pair on the central atom will have a ________ molecular geometry.

Question

Quizplus · Accepted Answer

The VSEPR model predicts the geometry of molecules based on the repulsion between electron pairs around the central atom. For a molecule with one lone pair and five bonded atoms (AB₅), the starting geometry is octahedral. However, with one lone pair taking up one position, the molecular geometry becomes square pyramidal.
