The molecular geometry of the PHCl₂ molecule is ________.

Question

Quizplus · Accepted Answer

The central atom in this molecule is P (phosphorus), which has five valence electrons. The molecule has two S atoms and one Cl atom as its ligands, with each having one valence electron to contribute. Thus, the total number of valence electrons in the molecule is 5+2+1 = 8. To determine the molecular geometry, we need to first draw the Lewis structure of the molecule. The Lewis structure of PHCl₂ is: Phosphorus has three bonded atoms and one lone pair of electrons, giving it a trigonal pyramidal geometry. Thus, the molecular geometry of PHCl₂ is also trigonal pyramidal. The correct answer is C.
