Give reason.
1.carbon compounds generally have low melting and boiling point.
2.carbon compounds generally do not conduct electricity.
Answers
1) Because they are bonded with covalent bond and the force of attraction in covalent bond is not strong enough.
2)They do not conduct electricity because they do not have free electron.Graphite is the only carbon compound that can conduct electricity
♤ Carbon can't lose 4 electron to form C^4+ ions as very high energy is required to remove 4 electrons.
♤ Carbon can not gain 4 electron to form C^4- ions as 6 protons can not hold 10 ♤ electrons and Energy needs to be supplied to overcome repulsion.
♤ Carbon can share 4 electron to form covalent compounds.
♤ Carbons do not conduct electricity as they are non - polar and do not form ions.
♤ They have low melting points and boiling points due to weak van der Waal's force of attraction between molecules
