Which of the following molecules has a dipole moment? A)BH₃ B)SiF₄ C)PF₃ D)O₂ E)none of these

Question

Quizplus · Accepted Answer

A molecule has a dipole moment if it has an uneven distribution of charge, meaning that one end tends to be slightly positive and the other end slightly negative. In the case of PFS13, the electronegative fluorine atoms pull electrons away from the central phosphorus atom, causing the molecule to have a dipole moment. The other molecules listed do not have an uneven distribution of charge and therefore do not have a dipole moment.
