Alright, guys, let's name that final functional group that was left on the bottom of the page. So here we have toe basically right out the formula for 246 Try metal nitrobenzene so bending involved. Go 123456 And really, you could start numbering anywhere you want. On two, there's a metal on four. There's a metal, and on six there's a metal. The nitro group theano to group doesn't get a number because it's on carbon number one. So drawing it this is what we will get as our example. And here we don't use or Thel Meta or Para, because that's only one to substitue. It's our on benzene because there'll be 12 to each other, Ortho or 13 to each other, meta or 1 40 each other para. When there's Mawr than to substitue, it's on benzene. We can't use it well, there's only one substitution on Benson. We can't use it. We can only use those terms if there's too substitutes on Benzie
