Which of the following is not a chiral?

A)  2-butanol

B)  2,3-dibromopentane

C)  3-bromopentane

D)  2-hydroxy propanoic acid

Correct Answer: C

Solution :

                In 3-bromopentane, there is no chiral C-atom, so it is not a chiral molecule. \[\underset{\begin{smallmatrix}  3-bromopen\tan e \\  It\,has\,no\,chiral\,C\,atom. \end{smallmatrix}}{\mathop{\overset{H}{\mathop{\overset{|}{\mathop{\underset{Br}{\mathop{\underset{|}{\mathop{C{{H}_{3}}-C{{H}_{2}}-C-C{{H}_{2}}-C{{H}_{3}}}}\,}}\,}}\,}}\,}}\,\]
