Oxidation state of carbon in HCOOH will be:

Oxidation state of carbon is not zero in

Oxidation state of carbon in its hydrides

(A): Oxidation state of carbon in C_(6)H_(12)O_(6) is zero. (R) : Oxidation state of carbon in all organic compounds is zero.

(A): Oxidation state of carbon in C_(6)H_(12)O_(6) is zero. (R) : Oxidation state of carbon in all organic compounds is zero.

Valency and Oxidation number are different for an element. Valency of carbon is generally 4, however, the oxidation state may be -4,-2 0,+2,-1 etc. In the compounds containing carbon. hydrogen and oxygen the oxidation number of carbon can be calculated as "Oxidation number of carbon"=(2n_(O)-n_(H))/(n_(C) Where, n_(H), n_(O) and n_(C) are number of respective atoms Oxidation state of carbon in diamond is:
