Use VSEPR theory to predict the geometry of the PCl₃ molecule. A) linear B) bent C) trigonal planar D) trigonal pyramidal E) tetrahedral

Question

Quizplus · Accepted Answer

For PClSBUSBU, the central P atom has 5 electron pairs (3 of which are bonded pairs with Cl and S, and 2 of which are lone pairs). According to VSEPR theory, this results in a trigonal bipyramidal electron pair geometry. However, since there are 2 lone pairs, the molecular geometry will be distorted and the molecule will have a trigonal pyramidal shape (similar to NH3).
