A solution contain three stereoisomers of 2,3-dihydroxy butanedioic acid. On fractional crystallization of this solution, two fractions. Fraction–I and Fraction–II are separated. Fraction-I on reaction with (+)-2-butanamine gives a single salt while Fraction-II on reaction with the same (+)-2-butanamine gives a mixture of two salts. Answer the following three questions based on the above information.
What can be accurately predicted about the molecules of fraction-I?
- Molecules of fraction-I are enantiomers
- Molecules of fraction-I are meso compound
- Molecules of fraction-I are in racemic form
- Molecules of fraction-I has no chiral centre
Answer
(B) Molecules of fraction-I are meso compound
