So once again, I begin labeling or numbering on my double bond because I want my double bond to have the lowest possible number value. So this guy is known as one cyclone because it's a cyclic compound, and we have six, so hexene. So one cyclohexine, or simply cyclohexine. So let's go to part E, or compound E. So once again, I want to label my compound in a way such that my double bond gets the lowest possible number value, and this methyl group also gets the lowest possible number value. So I begin on this side. So one carbon, second carbon, third carbon, fourth carbon, fifth carbon, 6th carbon.
