Which reaction produces an alkane by coupling two molecules of alkyl halide using metallic sodium in dry ether?
Answer and explanation
Correct answer: D. Wurtz reaction
The Wurtz reaction couples two alkyl halides in the presence of sodium metal in anhydrous ether to form a symmetrical alkane with double the carbon chain length: 2 R-X + 2 Na -> R-R + 2 NaX.
