Hey guys, so for this question it wants us to figure out if carbon is oxidized or neither. So, here we're looking at this carbon atom right here and comparing it to one of these. Now, in general chemistry we were used to calculating the oxidation numbers but for this question all we need to realize is we're going to look at our reagent and you see our carbon attached to a chlorine group, right? And for you is an electronegative atom is going to be more electronegative than carbon is. So, carbon is connected to an atom more electronegative than itself and our reactant and now let's take a look at what is connected to our product. So, in our product that looks like is connected to this silicon or silicon. Now, this molecule is going to be less than electronegative than carbon, so what that means is that carbon went from being attached to an electronegative atom that was more electronegative than itself and now was connected to an atom that's less electronegative themself, so what does that mean? it means that our carbon atom was reduced in our equation, okay? So, carbon was reduced. Now, let's answer that question for our silicon, that is going to be by itself there and now it's connected to a carbon, so it gained a bond, that means this compound is going to be oxidized. So, our silicon was oxidized, okay? So that is it for this question, I hope this makes sense and let me have you have any questions on our oxidizing and reducing compounds.
