Question

The oxidation state for carbon element in CO2 is:

a. +4

b. +5

c. +1

d. +3

Answer 1

Option A,+4

Step-by-step explanation:

Oxidation state of any element is the sum of oxidation of all elements =0

Here we need to find oxidation no of carbon and consider oxidation no of carbon as X and oxidation number of oxygen is -2

Then X+2(-2)=0 (since 2 oxygen atoms are there in CO2 )

X-4=0

X=+4
