Sugar is made of covalent bonds between nonmetals-carbon, hydrogen and oxygen. It exhibits some classic properties of covalent compounds; it is a brittle solid, it has a relatively low melting point and is a poor conductor of heat and electricity.
Types of Bonds Formed by Carbon - No, carbon doesn't only form covalent bonds. 1  Properties of Ionic and Covalent Compounds. 2  How Formulas of Ionic Compounds Work. 3  Use Electronegativity To Predict Ionic Bond Formation. 4  Know the Difference Between Ionic and Covalent Bonds. 5  Why the Formation of Ionic Compounds Is Exothermic.
