Polar Bonds

Polar molecules will dissolve in other polar molecules and nonpolar molecules will dissolve in other nonpolar molecules.

• True

• False

Polar molecules have

• no charges.

• slight positive and negative charges on opposite ends of the molecules.

• only positive charges.

• either positive or negative charges, but not both.
