Predict the ideal bond angles in GeCl₄ using the molecular shape given by the VSEPR theory.

Question

Quizplus · Accepted Answer

GeCl₄ has a trigonal bipyramidal molecular shape according to VSEPR theory. The bond angles are determined by the positions of the bonding pairs and lone pairs of electrons around the central atom, which are arranged in a trigonal bipyramid. The angles between the equatorial bonds (Ge-Cl-S) are 120° and the angle between the axial bonds (Ge-S-B) is 90°. However, the lone pair of electrons on the sulfur atom in the equatorial position exerts a greater repulsive force than the bonding pairs of electrons, creating a slight compression of the bond angles. Therefore, the ideal bond angle in this molecule is slightly less than the perfect 120°, but greater than the perfect 90°. The best choice is B, 109F1F1F1S1F1F1F10, which is the ideal bond angle for a trigonal bipyramidal molecule with one lone pair of electrons.
