Chirality rules
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. WebHowever, RR and RS have a different relationship. They are called diastereomers . Diastereomers are molecules with opposite chirality at some of the carbons and the same chirality at other carbons. A …
