Question

What makes water a polar molecule?

(Choice A)
It is able to dissolve nonpolar substances.
(Choice B)
It has fully positive and negative charges.
(Choice C)
It contains partial positive and negative charges.
(Choice D)
It contains ionic bonds.

Answer 1

Answer:

(CHOICE B)

Water is a polar molecule. While the overall charge of the molecule is neutral, the orientation of the two positively charged hydrogens (+1 each) at one end and the negatively charged oxygen (-2) at the other end give it two poles.

Answer 2

Answer:

(Choice C)

It contains partial positive and negative charges.

Explanation:

Unequal sharing of electrons makes water a polar molecule. This means that electrons spend a bit more time at the oxygen end of the molecule. This makes the oxygen end of the molecule slightly negative. Since the electrons are not near the hydrogen end as much, that end is slightly positive.
