13 Dear student The chemical bond formed by the sharing of
electrons between two atoms is known as a covalent bond The sharing
of electrons take place because each atom in the resulting molecule
wants to get stable inert gas configuration (octet rule) but it is
not possible through transfer of electrons in that particular
compound so the atoms tends to share electrons to complete their
octet Thus carbon forms covalent bonds, because it has 4 electrons
in its valence shell Thus option (a) is correct Please post the
remaining queries in separate threads Regards
