Rank compounds sucrose, naphthalene, benzoic acid, 2-naphathol, and phenol from highest to lowest melting point as you would predict based on type of intermolecular interaction. Explain.
highest melting point: benzoic acid
sucrose
2-naphthol
phenol
lowest melting point: naphthalene
Explanation: carboxylic acids have highest melting point due to the presence of hydrogen bonding. Hydrogen bonding is the strongest intermolecular forces of attraction which requires highest energy to break. so benzoic acid has highest melting point.
alcohols also contains hydrogen bonding so 2-naphthol has second highest melting point.
hydrocarbons have weak vanderwaal forces of attraction so they have lowest melting point.
