Why are most carbon compounds poor conductors of electricity…
Why are most carbon compounds poor conductors of electricity? Answer: The bonding in carbon compounds takes place by sharing of electrons i.e. covalent bonds are formed between the carbon atoms. Therefore, there are no free electrons which could carry the current as all are occupied in bonding. Hence, most of the compounds are poor conductors of electricity .

6.4: Ionic Bonding
Ionic solids are also poor conductors of electricity for the same reason—the strength of ionic bonds prevents ions from moving freely in the solid state. Most ionic solids, however, dissolve readily in water. Once dissolved or melted, ionic compounds are excellent conductors of electricity and heat because the ions can move about freely.
