Explain (in terms of shape and impact on intermolecular forces) why toluene would have a lower melting point than benzene even though it has higher molecular weight.

Thank you for the opportunity to help you with your question!

Melting point is related to the forces between molecule, Toluene  has a lower melting point because it has large methyl group,its symmetry or  shape allows molecules to have some space to move . Toluene structure has a poor stacking making it to have low melting point of -95

Benzene has a  high melting point because of better stacking of the molecules , the forces between molecules are kept together.

Please let me know if you need any clarification. I'm always happy to answer your questions.
