A solution contain three stereo-isomers of 2, 3-dihydroxy butanedioic acid. On fractional crystallisation of this solution, two fractions: Fraction-1 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 question based on the above information (a) Molecules of fraction-I are enantiomers (b) Molecules of fraction-I are meso compound (c) Molecules of fraction-I are in racemic form (d) Molecules of fraction-I has no chiral centre What is the relationship between the molecules of fraction-I with the molecules of fraction-II?
