# What is the C oxidation state, O oxidation state, and the H oxidation state?

Refer below.

#### Explanation:

In $C {H}_{4}$ , oxidation state of $C$ is -4 while $H$ has oxidation state $+ 1$.

In general,

1. CARBON: Oxidation state of carbon can vary widely, from $- 4$ (in $C {H}_{4}$) to $+ 4$ (such as in $C {O}_{2}$).
2. OXYGEN: The oxidation state of oxygen in its compounds is -2, except for peroxides like ${H}_{2} {O}_{2}$, and $N {a}_{2} {O}_{2}$, in which the oxidation state for $O$ is $- 1$.
3. HYDROGEN: The oxidation state of hydrogen is $+ 1$ in its compounds, except for metal hydrides, such as $N a H$, $L i H$, etc., in which the oxidation state for H is $- 1$.
