Question

Someone plz help me​

Answer 1

Carbon can not afford More negative charge on itself because of Low E.N value like Halogens. That's why tertiary Carboanion is more unstable as compared to primary carboanion. It depends on its ionization. A normal carbon atom has a net neutral charge because the electrons balance out the protons.

Answer 2

i) Carbon cannot form C4+ cation as it requires too much energy to remove all the valence electrons

ii) Carbon cannot form C4- anion as the nucleus cannot hold 4 more electrons in its outermost shell.

Thus it forms compounds by sharing electrons, which are called covalent compounds.

Covalent compounds are bad conductors of electricity as they do not contain ions, which help in conduction

They have low melting and boiling points as the intermolecular forces of attraction are less.

Please note that the intramolecular forces of attraction are strong.

Hope this helped!
