Explain why carbon compounds generally have low melting and boiling point
Answers
Carbon compounds have low boiling and melting point because carbon combines with other elements with the sharing of electrons and thus form covalent bond. And covalent compounds are made made up of electrically neutral molecules. So the force of attraction between the molecules of covalent compound is very weaks. Only a small amiunt of heat energy is required to break these weak molecular forces. Thereforebcarbon compounds have low boiling and melting point.
♤ 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
