Question

Quizplus · Accepted Answer

The molecule SCl₂ has a trigonal bipyramidal molecular geometry (based on the VSEPR theory). The axial bonds are arranged at a 180° angle from each other, while the equatorial bonds are arranged at a 120° angle from each other. The bond angle between an axial bond and an equatorial bond is expected to be less than 120° but more than the ideal tetrahedral angle of 109.5° due to the electron-electron repulsion caused by the lone pairs on the equatorial atoms. Therefore, the bond angles in SCl₂ are expected to be a little less than 109.5°, making choice A the best answer.
