Sodium chloride is a solid having high melting point but carbon tetrachloride is a liquid-why?

Explanation

NaCl is an ionic compound. In the crystal of NaCl, the oppositely charged `Na^(+) and Cl^(-)` are held together by strong electrostatic forces of attraction. Hence a large amount of energy is required to bring the ions into the liquid state. Hence, sodium chloride is a solid having high melting point carbon tetrachloride `(C Cl_(4))`, on the other hand, consists of non-polar covalent molecular and the only force and operates among the molecules is the weak van der waals' forces. so, the molecules are weakly held together. hence, carbon tetrachloride has very low melting point and it is liquid at ordinary temperature.
