Which of these molecules have a dipole moment? A) PCl₅ and SiCl₄ B) POCl₃, SO₂Cl₂, and SO₃ C) POCl₃ and SO₂Cl₂ D) PCl₅, POCl₃, SOCl₂, SO₃, and SiCl₄ E) PCl₅, SF₆, SO₃, and SiCl₄

Question

Quizplus · Accepted Answer

Both POCl3 and SOCl2 molecules have a dipole moment due to the presence of polar bonds and the asymmetrical arrangement of atoms around the central atom. The molecule SO2Cl2 also has polar bonds, but its symmetrical arrangement cancels out the dipole moment. SiCl4 is a symmetrical tetrahedral molecule and does not have a dipole moment.
