How many enantiomer pairs are obtained by monochlorination of 2, 3-dimethylbutane

Options

A. Nil
B. Four
C. Two
D. One

Answer

D

Explanation

`CH_(3) - underset(CH_(3))underset(|)( C)H - underset(CH_(3))underset(|)( C)H - CH_(3) + Cl_(2) to CH_(3) - underset(CH_(3))underset(|)( C)H - overset(**)underset(CH_(3))underset(|)( C) H - CH_(2) Cl`
Due to the presence of chiral carbon it shows the optical activity and its mirror image are non superimposable so it shows one enantiomer pair.
