In an ionic compound, ions are attracted to each other as a result of their charges. In a covalent compound, molecules are attracted to each other as a result of weaker intermolecular forces. Given this information, which of the following substances likely has the highest melting point? A. carbon dioxide B. hydrogen C. carbon tetrachloride D. sodium chloride
since NaCl is an ionic bond the molecules are attracted to each other by strong bonds, making it difficult to melt and thus rendering it the highest melting point
