What is the oxidation number of CH2Cl2?

To find the oxidation number of each element in CH2Cl2, we look at the electronegativity of each element. Carbon typically has an oxidation number of +4, hydrogen +1, and chlorine -1. Hence, the oxidation numbers in CH2Cl2 would be +4 for carbon, +1 for each hydrogen, and -1 for each chlorine.
