Which of the following statements is (or are) true?

I. All polar molecules have dipole moments.
II. All polar molecules have oppositely charged regions.
III. A polar molecule is attracted to other molecules because of electrostatic forces.
IV. All polar molecules have hydrogen bonding.
A. I and II only
B. I, II, and IV only
C. II, III, and IV only
D. I, II, and III only

I believe the answer is A or D

  1. I believe I is true.
    I think II is true.
    III is true sometimes but not always. I would agree if it said attracted to other polar molecules. It doesn't say that so I would rule III out.
    IV is not true.
