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. WebThe racemic mixture is 7 % (+)-cholesterol and 7 % (-)-cholesterol. It will have zero optically activity, so all of the observed rotation comes from the 86 % natural cholesterol. The natural cholesterol then accounts for 86 % + 7 % = 93 % of the mixture. Comment on Ernest Zinck's post “That's correct.
