The larger, higher molecular weight molecule would have a higher melting point because of greater dispersion forces present.
What is a hydrocarbon?
A hydrocarbon is a compound that contains carbon and hydrogen. Since hydrocarbons are nonpolar molecules, the only kind of intermolecular forces present are the dispersion forces.
Hence, when comparing 2 hydrocarbons, the larger, higher molecular weight molecule would have a higher melting point because of greater dispersion forces present.
