Oxidation number of C in C6H6?

Answer 1

'4' .

Carbon atoms have four electrons in their outer energy shell. This leaves space to accept four more electrons to formvfour covalent bonds.

The oxidation number refers to the number of electrons in the outer energy shell that are used in combination with other atoms. Since carbon uses all four electrons , then its oxidation number is '4'.

Other elements, notably nitrogen have variable oxidation number.

Nitrgen when combined with hydrogen to form ammonia has an oxidation number of '3'. Because only three electrons out of the five electrons , in the outer energy shell, are used in combination with hydrogen.

Answer 2

The oxidation number of carbon (C) in C6H6 is 0 because carbon exhibits a zero oxidation state in organic compounds where it is bonded to itself or to hydrogen atoms. In this case, each carbon atom in C6H6 is bonded to other carbon atoms or hydrogen atoms only, resulting in an oxidation state of 0.
