Question

Find the oxidation state of the underlined

elements in each of the
the
following substance
CH4

Answer 1

-4

Step-by-step explanation:

the oxidation number of hydrogen is +1

since there are 4 hydrogen the oxidation number contribution of H is 4

The sum of oxidation number of a charge less compound is always 0

so

C+4×H=0

by general algebra we obtain C= -4.
