Question

Eight grams of racemic alpha-methylbenzylamine was resolved into enantiomers by crystallization of its diastereomeric salts of L-(+)-tartaric acid, followed by neutralization. The isolated (S)-(-)-enantiomer was distilled in vacuum to give 1.5 g of pure amine. Calculate the yield of (S)-(-)-alpha-methylbenzylamine

Eight grams of racemic alpha-methylbenzylamine was resolved into enantiomers by crystallization of its diastereomeric salts of L-(+)-tartaric acid, followed by neutralization. The isolated (S)-(-)-enantiomer was distilled in vacuum to give 1.5 g of pure amine. Calculate the yield of (S)-(-)-alpha-methylbenzylamine 19 % 25 % 38 % 55 % 63 %

Explanation / Answer

If we get 4 gm that is 100% Yield

here we got 1.5 gm hence = 1.5 x100/4 = 37.5% ~38% Yield
