D)F-F
E)all of the above

Question

Quizplus · Accepted Answer

A dipole moment is generated when there is an asymmetric distribution of electrons in a molecule. In H-F, the electrons are more towards F, giving it a partial negative charge, and H gets a partial positive charge. Hence, it is a polar covalent bond and has a dipole moment. Cl-Cl and F-F have a symmetrical distribution of electrons and are nonpolar; thus, they do not have a dipole moment. In H-H, the bond is nonpolar because the atoms on each side have the same electronegativity and the electrons are shared equally.
