Para and ortho position

WebTo figure that out you have to look at your substituents and see what kind of directors they are. So we'll start right here with this methyl group, which we know is an ortho para … WebAnd so the meta product dominates here, not the ortho/para. Let's see if we can figure out why by looking at some resonance structures for this mechanism. And so we'll start with and ortho attack. So in our first example here we'll do an ortho attack where we add the nitro group onto the ortho position.
