Refer below.

Explanation:

In CH_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 CH_4) to +4 (such as in CO_2).
  2. OXYGEN: The oxidation state of oxygen in its compounds is -2, except for peroxides like H_2O_2, and Na_2O_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 NaH, LiH, etc., in which the oxidation state for H is -1.
