Question 11

molecules have a positive area and a negative area.

a)polar

b)nonpolar

c)organic

d)gaseous

Polar molecules have a positive and a negative area.

Explanation:

Polar molecules contain polar bonds because of the difference in electronegativity between the arms that are bonded. These molecules are net dipole because of opposing charges.  

An example of a polar molecule is water. It has both positive and negative charges on each side. The dipole in water does not cancel. Thus, making water like a net dipole molecule. Because of the polar nature of water, other polar molecules dissolve in water.
