Answer

No. No. Yes.

Work Step by Step

Diatomic molecules with identical components do not have a permanent dipole moment; the outer electrons are shared equally. However, the water molecule does have a permanent dipole moment, as seen in Figure 29-6. Oxygen has a greater affinity for electrons than does hydrogen, so each hydrogen has a small net positive charge and oxygen has a small net negative charge. One end of the molecule will be positively charged and the other end will be negatively charged, resulting in a polar molecule (i.e., one with a permanent dipole moment).
