Which of the following alkyl chlorides on Wurtz reaction gives 2, 2, 5, 5- tetramethylhexane ?

Step-by-step solution

Wurtz reaction involves the coupling of two alkyl halide molecules in the presence of sodium and dry ether to form a symmetrical alkane. 2 R-Cl + 2 Na dry ether R-R + 2 NaCl The given product is 2,2,5,5-tetramethylhexane. Its structure is ( CH ₃)₃ C - CH ₂- CH ₂- C ( CH ₃)₃ . Cleaving the molecule symmetrically at the central C - C bond gives two identical alkyl groups, which are neopentyl groups, ( CH ₃)₃ C - CH ₂- . Therefore, the required alkyl chloride is neopentyl chloride, ( CH ₃)₃ C - CH ₂- Cl . Answer: ( CH
