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

A molecule has a dipole moment if it has a separation of positive and negative charges, meaning it is polar. In this case, POCl3 and SOCl2 are polar molecules while SiCl4 is nonpolar. SOSCl2 is also polar due to the presence of the S-O bond. Therefore, the correct answer is choice C, which includes only the polar molecules POCl3 and SOCl2.
