What is the oxidation state of each element in COH2?

first of all will find for carbon

so x + (-2) + (1*2) = 0. x=0

carbon=0.

For oxygen it will b

; 4+x+1*2=0, x=-6.

Oxygen=-6. and finally

For hydrogen;

4 + (-2) + x*2=0; x=-1.

Hydrogen=-1.

and the overall oxidation state of molecule is zeroo and it is a neutral compound
