Acetone and sodium chloride both have similiar mass. explain why their other properties differ.

acetone: c3h6o, melting point = −94°c, liquid at room temperature, low electrical conductivity

sodium chloride: nacl, melting point = 801°c, solid at room temperature, high electrical conductivity

Acetone is a covalent compound, whereas sodium chloride is an ionic compound.

Covalent compounds have strong bonds that do not break apart like ionic compounds do, and they do not conduct electric charge in solution.

Covalent compounds do not have strong attractions between molecules and so have very low melting points, unlike ionic compounds.
