                Which of the following is not chiral?                                                                                                       

A)                  2-butanol                                                          

B)                  2, 3-dibromopentane   

C)                  3-bromopentane           

D)                  2-hydroxypropanoic acid

Correct Answer: C

Solution :

                                          2-butanol                                 2, 3-dibromopentane                                 3-bromopentane                                                  2-hydroxy propanoic acid                                 Hence, in these 3-bromopentane is not a chiral molecule due to absence of chiral ?C? atom.
