Concept:Wurtz reaction: two alkyl halide molecules couple in dry ether using sodium metal, forming a higher alkane.
Explanation:The given alkyl halide is 2-chloro-2-methylbutane.
Its structure is:
(CH3​)2​C(Cl)CH2​CH3​In the Wurtz reaction, two such molecules combine after chlorine is removed as
NaCl.
Two alkyl groups join at the carbon atoms that originally carried chlorine:
(CH3​)2​C(CH2​CH3​)−C(CH2​CH3​)(CH3​)2​Number the longest carbon chain from one end to the other:
The chain is
CH3​CH2​−C−C−CH2​CH3​ with four methyl substituents.
The longest chain contains 6 carbons, so the parent alkane is hexane.
The methyl groups are located at positions 3 and 4, two on each carbon.
Hence, the product is:
3,3,4,4-tetramethylhexaneAnswer:Option D: 3,3,4,4-tetramethylhexane.
