The video tutorial explains how to find the oxidation number for carbon in C3O2, a neutral compound. It begins by calculating the average oxidation number for carbon, which results in a fractional value. The tutorial then explains why this fractional oxidation number occurs, highlighting the difference between the central and terminal carbon atoms. The central carbon has an oxidation state of zero, while the terminal carbons have a state of +2, leading to the average fractional value. The video concludes with a summary of these findings.
