Vedclass · Answer

(D) When $\omega$-dihalides (terminal dihalides) react with sodium metal in the presence of dry ether,an intramolecular Wurtz reaction occurs,leading to the formation of a cyclic hydrocarbon.For example,$1, 4-$dibromobutane reacts with $2Na$ to form cyclobutane and $2NaBr$ as a byproduct.The reaction is: $Br-CH_2-CH_2-CH_2-CH_2-Br + 2Na ightarrow 	ext{Cyclobutane} + 2NaBr$.
