If water were a non polar molecule, how would its properties be different?

A.) water would be a much lighter molecule

B.) water would be able to climb up inside plants

C.) water would not be able to form hydrogen bonds

D.) water would stick together much more strongly

The answer would be C.

Nonpolar molecules cannot form hydrogen bonds that polar molecules can. Interactions between nonpolar molecules are very weak thus D is wrong. And water can climb up inside plants and has adhesion and cohesion because of it's strong hydrogen bonds.
