Question

The racemic mixture of Alanine $\left(\text{C}{\text{H}}_{\text{3}}\underset{N{H}_2}{\underset{|}{\text{C}}\text{H}}\text{- COOH}\right)$ can be resolved by using:
(a) (+)-2-Butanol
(b) (l) -2-Chlorobutanoic acid
(c) $(\pm )$-2-Butanol
(d) (dl mix)-2-Chlorobutanoic acid

• A. a and b only
• B. a and c only
• C. b and d only
• D. a and d only

Answer 1

The correct option is A a and b only

Racemic mixtures can be resolved by pure compound having either d or l stereo i.e either $(+)$ or$(-)$.So,$(+)-2$-butanol and $\left(1\right)-2$-chlorobutanoic acid can be used.
