D) Three

E) One

Show Answer

Answer:

Correct Answer: E

Solution:

$\underset{2, 3-dimethyl butane}{C H_{3} - \underset{C H_{3}}{\underset{|}{C}, H -}, \underset{C H_{3}}{\underset{|}{C}, H -}, C H_{3} + C l_{2}}, \to$

$\underset{2, 3-dimethyl chloro butane}{C H_{3} - \underset{C H_{3}}{\underset{|}{C}, H -}, \underset{C H_{3}}{\underset{|}{\overset{∙}{C}}, H -}, C H_{2} C l},$ 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.

$\begin{matrix} \underset{(I)}{C H_{3} - \underset{C H_{3}}{\underset{|}{C}, H -} \underset{C H_{3}}{\underset{|}{C}, H -}, C H_{2} C l}, & \underset{(I I)}{C l C H_{2} - \underset{C H_{3}}{\underset{|}{C}, H -}, \underset{C H_{3}}{\underset{|}{C}, H -}, C H_{3}}, \end{matrix}$
