Two molecules, A and B, have very different physical properties. A and B do not mix. Molecule A boils at 82 C and freezes at 0 C. Molecule B boils at 38 C and freezes at -68 C. Which molecule has the higher total intermolecular forces?

Respuesta :

Answer:

Molecule A

Explanation:

Molecules with the stronger intermolecular forces are pulled tightly together  to form solid at higher temperatures and that's why the freezing point is higher.

Also, molecules with the stronger intermolecular force have greater interaction between the molecules and thus on heating do not boil easily and have high boiling point also.

So, Molecule A has boiling point and melting point both greater than molecule A . So, it has the higher total intermolecular forces.
