Which of these molecules have a dipole moment?

Question

Quizplus · Accepted Answer

POCl3 and SOCl2 have dipole moments due to the asymmetric arrangement of their atoms. Cl and O are more electronegative than their adjacent atoms, resulting in partial negative charges on those atoms and partial positive charges on the adjacent ones, leading to a net dipole moment. SiCl4 does not have a dipole moment as the four Cl atoms are symmetrically arranged around the central Si atom, leading to a cancelation of any dipole moment.
