The bond angle in H₂Se is

Question

Quizplus · Accepted Answer

The molecule H₂Se has a trigonal bipyramidal shape with one lone pair on the equatorial position. The bond angles in a trigonal bipyramidal shape are 90° and 120° for the axial and equatorial positions, respectively. However, the presence of a lone pair in the equatorial position causes a repulsion that pushes the bonded pairs closer together, leading to a decrease in bond angle. Therefore, the bond angle in this molecule is expected to be less than 120°, and option B (<104.5°) is the best choice.
