1.	Explain the structure of diamond giving the reason for its harness as well as non conductivity of electricity.
Answer» Solution :Non-CONDUCTOR of electricity : All the FOUR electrons present in the valence shell of carbon atoms are used up in `sp^(3)` hybridisation and form sigma bonds . No mobile electrons are left in the diamond crystals to allow the conduction of electricity. Hence diamond is a non - conductor of electricity. Extremely hard : Due to HIGH strength of covalent bonds HOLDING all the carbon atoms in diamond together , diamond is very hard . Infact diamond is the hardest substance known.
