So once again, I have a 6th carbon ring. And so I named this guy. So, notice that my methyl group is found on the third carbon. So I name it three methyl, one cycloxine. So three methyl simply means our methyl group is in the third carbon, and one cyclohexine means that my double bond is found on the first carbon, and we have a ring. So finally, we get to compound E. So in compound E, we have a cyclic six carbon backbone, and we have three double bonds.
