Question

The reaction that yields predominantly one enantiomer of a possible pair is called ____________

(a) Dynamicselective

(b) Stereoselective

(c) Regioselective

(d) Stereospecific

This question was addressed to me during an internship interview.

Origin of the question is Stereoselectivity and Stereospecificity in portion Structure and Stereostructure of Molecules of Engineering Chemistry I

Answer 1

The correct choice is (b) Stereoselective

For explanation I would say: The reaction that yields predominantly one enantiomer of a possible pair is called stereoselective reaction. Stereoselectivity is the property of a chemical reaction in which a single reactant forms an unequal mixture of stereo isomers during the non-stereo specific creation of a new stereo center or during the non-stereo specific transformation of a pre-existing one.
