Why are most carbon compounds have low melting and boiling point
Answers
As Carbon forms co-valent bonds because it has 4 electrons in the outermost shell. These bonds have weak inter molecular force of attraction, hence it is easy to break the co-valent bond just by heating the carbon compound. Hence carbon compounds have low melting and boiling points.
Hope this helps you :)
♤ 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
