    anhydrous calcium chloride is formed by ionic bonding. Ionic compounds have strong electrostatic bonds between particles. As a result, they generally have high melting and boiling points.

    methylbenzene is formed by covalent bonding. Covalent compounds form distinct molecules, in which the atoms are bound tightly to one another. Unlike in ionic compounds, these molecules don't interact with each other much (except through relatively weak forces called "intermolecular forces"), making them very easy to pull apart from each other. Since they're easy to separate, covalent compounds have low melting and boiling points.

    The first and basic difference between this two compounds is - calcium chloride is an Inorganic Salt, Methyl benzene is an Organic Compound. Most Inorganic Salts and Compounds have much higher melting point then any Organic Compounds.

Unlike in ionic compounds, these molecules do not attract each other making them very easy to pull apart from each other. Since atoms or group of atoms can easily change their position in the molecule, covalent compounds have low melting and boiling points.
