Question

How do you know when the oxidation of carbon changes according to the respective element?

Answer 1

Answer:

n a C-H bond, the H is treated as if it has an oxidation state of +1. This means that every C-H bond will decrease the oxidation state of carbon by 1.

For carbon bonded to a more electronegative non-metal X, such as nitrogen, oxygen, sulfur or the halogens, each C-X bond will increase the oxidation state of the carbon by 1. (Certain non-metals are less electronegative than carbon, such as phosphorus, silicon or boron, but bonds from carbon to these elements are much less common.)

For carbon bonded to another carbon, the oxidation state is unaffected.  So a carbon attached to 4 carbons has an oxidation state of zero.

Answer 2

Answer:

depending on the oxidation state of the other element and the type of bond

Explanation:

Carbon has atomic number 6, that means it. an have 2 electrons in the first shell and 4 electrons in the next energy level. So it can maximum lose 4 electrons and become +4 state, or at max it can gain 4 electrons go become -4 state. since the 2nd shell can have max of 8 electrons.

now we know the range -4 to +4 C atom can show these oxidstion states .
