Vedclass · Answer

(D) The Wurtz reaction or similar reductive coupling reactions using $Na$ or $Zn$ require the halogen atoms to be positioned such that a ring closure or elimination can occur. In option $D$,the reaction of $1,3$-dibromocyclobutane with $Na$ in dry ether typically leads to the formation of bicyclo[$1.1$.$0$]butane,not cyclobutene. Cyclobutene is formed by the elimination of $HBr$ or similar processes,whereas the intramolecular Wurtz reaction of $1,3$-dihalides forms a bicyclic structure. Therefore,the product shown in option $D$ (cyclobutene) is incorrect as the major product for that specific reaction.
