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.
