Question

why did you have to form a diastereomeric salt from one of the enantiomers of ibuprofen? Choose two 13 It is extremely dangerous to isolate ibuprofen without forming the salts. e The direction that each diastereomeric salt rotates polarized light can be measured and and is used to analyze the enantiomeric composition of the original sample The diastereomeric salts have differing solubilities that will allow us to isolate one enantiomer. It is virtually impossible to separate enantiomers directly

Explanation / Answer

A diastereomeric salt is formed from one of the enantiomers of ibuprofen due to:

1) The direction that each diastereomeric salt rotates polarized light can be measured and is used to analyse tha enantiomeric composition of the original sample

2) The diasteromeric salts have differing solubilities that will allow us to isolate one enantiomer
