Why do nonpolar compounds tend to have lower melting points and boiling points than polar compounds?

A. Polar molecules have ionic bonds between them.

B. Polar molecules have metallic bonding.

C. Nonpolar molecules have weaker covalent bonds within them.

D. Nonpolar molecules only have Van der Waals forces between them.

C

Explanation: Polar molecules differ from nonpolar molecules by having positive and negative ends and stronger intermolecular forces of attraction Nonpolar molecules have only weak attractive forces for each other, so nonpolar substances tend to have low melting points and boiling points

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .

be subject to a force andchange its motion
