Which of the following molecules is polar?

Question

Quizplus · Accepted Answer

A molecule is polar if it has a net dipole moment, which occurs when there is an uneven distribution of electrons. In option B, there is a difference in electronegativity between chlorine and hydrogen, causing a dipole moment in the molecule. In option A, there is no difference in electronegativity between the two atoms, and in option C and D, there are only nonpolar covalent bonds present, resulting in no net dipole moment.
