mixture of enantiomers has a specific rotation of -25 degrees when its pure enantiomers have a specific rotation of ± 30 degrees, what is the percent composition of the major enantiomer?  Round to the nearest whole number.

2. For each pair of structures shown, indicate whether the two species are constitutional isomers, enantiomers, diastereomers of one another, or identical molecules. For each structure draw Fisher projection. a) b) d) e) f) *~*=*= K‡ Br H₂CO H₂CO H₂CO H₂CO H₂CO H H H H₂CO H₂CO Hilma K=H‡ Br H H Br H Br H Gall Br H H₂CO = way = Br K‡ H H₂CO Br Br Br g= H H = wait ‡ # H₂CO Camiler H₂CO Br K‡
