Vedclass · Answer

(D) The reaction of $1-Bromo-3-chloro$ cyclobutane with two equivalents of metallic sodium in ether is an intramolecular Wurtz reaction.Sodium acts as a reducing agent,donating electrons to the carbon atoms bonded to the halogen atoms.This leads to the formation of a carbanion at the carbon bearing the bromine atom,which then performs an intramolecular nucleophilic substitution ($S_N2$ type) on the carbon bearing the chlorine atom.This results in the formation of a new carbon-carbon bond,closing the ring to form bicyclo$[1.1.0]$butane.The correct option is $D$.
