प्रश्न
Why are most carbon compounds poor conductors of electricity?
उत्तर
Covalent compounds do not conduct electricity because they do not have free electrons. Current results from the motion of electrons or ions. Also, on dissolving covalent compounds in water they do not form ions. So, covalent compounds are generally poor conductor of electricity.
