A

CH3(CH2)3BrCH_3(CH_2)_3Br

B

CH3(CH2)5BrCH_3(CH_2)_5Br

C

CH3(CH2)3CH(Br)CH3CH_3(CH_2)_3CH(Br)CH_3

D

CH3−(CH2)2−CH(Br)−CH2−CH3CH_3-(CH_2)_2 - CH(Br) - CH_2 - CH_3

Answer

CH3−(CH2)2−CH(Br)−CH2−CH3CH_3-(CH_2)_2 - CH(Br) - CH_2 - CH_3

Explanation

Solution

Alkyl halides react with metallic NaNa in presence of dry ether to form symmetrical alkanes containing double the number of carbon atoms present in the alkyl halide.

This reaction is called Wurtz reaction
