WebChirality emerges from the existence of two non-superimposable mirror images of a given molecular structure. ‘Conventionally, we only tend to consider the chirality of molecules … WebThe name of the first molecule is (R)-4-methylcyclohexene. The 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.
