## Fraction of Minor Isomer Solution

STEP 0: Pre-Calculation Summary
Formula Used
Mole Fraction of S = 50-(Percent Enantiomeric Excess/2)
FS = 50-(%ee/2)
This formula uses 2 Variables
Variables Used
Mole Fraction of S - Mole Fraction of S 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
STEP 2: Evaluate Formula
Substituting Input Values in Formula
FS = 50-(%ee/2) --> 50-(40/2)

Percent Enantiomeric Excess Considering Amount of Enantiomer
Percent Enantiomeric Excess = (abs(Moles of R-Moles of S)/(Moles of R+Moles of S))*100
Specific Rotation of Optically Active Compound
Specific Rotation = Observed Rotation/(Length Of Sample Tube*Concentration of Solution in Polarimeter)
Percent Enantiomeric Excess
Percent Enantiomeric Excess = abs(Mole Fraction of R-Mole Fraction of S)*100
Enantiomeric Excess
Enantiomeric Excess = abs(Mole Fraction of R-Mole Fraction of S)
Optical Purity
Optical Purity = (Observed Specific Rotation/Maximum Specific Rotation)*100
Fraction of Major Isomer
Mole Fraction of R = 50+(Percent Enantiomeric Excess/2)
Fraction of Minor Isomer
Mole Fraction of S = 50-(Percent Enantiomeric Excess/2)

## Fraction of Minor Isomer Formula

Mole Fraction of S = 50-(Percent Enantiomeric Excess/2)
FS = 50-(%ee/2)

## 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.
