Bicyclobutane

Vedclass · Answer

(A) The reaction of a dihaloalkane with sodium in ether is an intramolecular Wurtz reaction.In $1$-bromo-$3$-chlorocyclobutane,the halogen atoms are at positions $1$ and $3$.When treated with $2$ equivalents of sodium,the sodium atoms remove the halogen atoms,leading to the formation of a new carbon-carbon bond between the $1$ and $3$ positions.This results in the formation of bicyclo[$1.1.0$]butane.Thus,the correct product is bicyclobutane.
