WebMay 5, 2024 · Oxygen, halogens, and carbons on double or triple bonds can’t be chiral centers as they can’t have bonds to four different groups. Any molecule with chiral centers are mirror images of each other, but they are non-superimposable. 2. List out the groups or substituents. List out the groups attached to the carbon atom. Look at the … WebThe double bond gets priority in the naming, and the numbers must include both alkene carbon atoms. So C-1 is at the bottom, C-2 is at the 4-o'clock position, and the methyl group is on C-4. The name of the second molecule is (S)-3-bromo-3-chloro-2-methylpentane. You forgot the methyl group.
