Calculate enantiomeric axcees of mixture containing 6g of (+) 2-butanol and 4g of (-) 2-butanol.

Calculate enantiomeric excees of mixture containing 6g of (+) 2-butanol and 4g of (-) -2-butanol.

The enantiomeric excess and observed rotation of a mixture containing 6 gm of (+)-2-butanol and 4 gm of (-)-2-butanol are respectively (if the specific rotation of enantiomerically pure (+)-2-butanol is +13.5 unit).

Dehydration of 2-butanol gives

4-dimethylamino-2-butanol
