Question

Graphite is a good conductor of heat and electricity and Diamond is not but But they both are allotrope of carbon why Diamond is not a good conductor of heat and electricity​

Answer 1

Answer:

Why does graphite conduct electricity while diamond does not even if ... In a graphite molecule, one valence electron of each carbon atom remains free, Thus making graphite a good conductor of electricity. Whereas in diamond, they have no free mobile electron. Hence there won't be flow of electrons That is the reason behind diamond are bad conductor electricity.

In diamond, each C-atom is sp3 hybridised and is tetrahedrally bonded to four carbon atoms. Diamond does not have free electrons. Since the conduction of electricity requires the presence of free electrons, diamond is a bad conductor of electricity.
