what are the basic properties of
Covalent compounds?
Answers
Answer:
Covalent compounds have bonds where electrons are shared between atoms. Due to the sharing of electrons, they exhibit characteristic physical properties that include lower melting points and electrical conductivity compared to ionic compounds.
Answer:
Covalent compounds have bonds where electrons are shared between atoms. Due to the sharing of electrons, they exhibit characteristic physical properties that include lower melting points and electrical conductivity compared to ionic compounds.Low melting points and boiling points. A relatively small amount of energy is required to overcome the weak attractions between covalent molecules, so these compounds melt and boil at much lower temperatures than metallic and ionic compounds do. In fact, many compounds in this class are liquids or gases at room temperature.
Low enthalpies of fusion and vaporization These properties are usually one or two orders of magnitude smaller than they are for ionic compounds.
Soft or brittle solid forms. The weak intermolecular forces makes the solid form of covalent molecular compounds easy to distort or break.
Poor electrical and thermal conductivity. Ionic compounds conduct electricty well when melted; metallic solids do as well. Covalent molecular compounds do not.
