Fraction of Major Isomer Solution

STEP 0: Pre-Calculation Summary

Formula Used

Mole Fraction of R = 50+(Percent Enantiomeric Excess/2)
F_R = 50+(%ee/2)
This formula uses 2 Variables

Variables Used

Mole Fraction of R - Mole Fraction of R is a quantity defined as the ratio between the amount of a constituent substance and the total amount of all constituents in a mixture.
Percent Enantiomeric Excess - Percent Enantiomeric Excess is a measurement of purity used for chiral substances. It reflects the percent to which a sample contains one enantiomer in greater amounts than the other.

STEP 1: Convert Input(s) to Base Unit

Percent Enantiomeric Excess: 40 --> No Conversion Required

What are R and S?

To name the enantiomers of a compound unambiguously, their names must include the "handedness" of the molecule. The method for this is formally known as R/S nomenclature. The letters "R" and "S" are determined by applying the Cahn-Ingold-Prelog (CIP) rules. The optical activity (+/-) can also be communicated in the name, but must be empirically derived.
