A sample of optically active alochol has a specific ratation, `[alpha]_(D)^(25)`, equal to `+1.51^(@)`. a. What is the percentage enantiomeric excess of the sample? b. Which enantiomer is in excess, `(R ) or (S)`? |
|
Answer» a. Enantiomeric excess `= ("Observed rotation")/("Specific rotation of pure enantiomer")xx100` `=(+1.151^(@))/(+5.756^(@))xx100= 20.00%` b. Since the (R ) enantiomer is `(+)`-from, it is present in excess |
