Solution
Correct Answer:
n-Butane
In Wurtz reaction, two alkyl halide molecules couple in presence of sodium and dry ether: 2 C2H5Br + 2 Na -> C4H10 + 2 NaBr. Coupling of two ethyl groups gives n-butane. The carbon count sanity check also confirms 2 + 2 = 4 carbons in product.
This easy difficulty chemistry question is from the chapter organic compounds containing halogens, covering the topic of wurtz reaction. It appeared in the 2025 exam.
