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.
The bonds of the ionic compounds are more crystal-like than the bonds of the covalent compound. Therefore, covalent compounds are softer, and more flexible. Covalent compounds are also more flammable than ionic compounds, due to the fact that they often contain Carbon and Hydrogen.
