Chemistry Question on Haloalkanes and Haloarenes

Which of the following compounds is not chiral ?

A

DCH2CH2CH2CIDCH_2CH_2CH_2CI

B

CH3CH2CHDCICH_3CH_2CHDCI

C

CH3CHDCH2CICH_3CHDCH_2CI

D

CH3CHCICH2DCH_3CHCICH_2D

Answer

DCH2CH2CH2CIDCH_2CH_2CH_2CI

Explanation

Solution

Chiral carbon is that carbon whose all the four
valencies are satisfied by four different groups.
Due to absence of asymmetric (chiral) C- atom
DCH2CH2CH2CI\, \, \, \, \, \, \, \, D - CH_2 - CH_2 - CH_2CI
molecule is not a chiral molecule.
