QuestionDiscuss the melting point trend for pentane ($-129^{\circ} \mathrm{C}$), diethyl ether ($-116^{\circ} \mathrm{C}$), and 1-butanol ($-90^{\circ} \mathrm{C}$).

Studdy Solution
In conclusion, the trend in melting points can be explained by the strength of the intermolecular forces in each compound. Pentane, which only has London dispersion forces, has the lowest melting point. Diethyl ether, which has London dispersion forces and dipole-dipole forces, has a higher melting point.1-butanol, which has London dispersion forces, dipole-dipole forces, and hydrogen bonding, has the highest melting point.
