Vedclass · Answer

(C) When $1,3-$dibromopropane $(Br-CH_2-CH_2-CH_2-Br)$ is heated with zinc dust in an ether solvent,an intramolecular dehalogenation reaction occurs.Zinc acts as a reducing agent and removes the two bromine atoms from the terminal carbons.The two terminal carbon atoms then bond together to form a three-membered ring.The reaction is: $Br-CH_2-CH_2-CH_2-Br + Zn \xrightarrow{	ext{ether}} 	ext{cyclopropane} + ZnBr_2$.Thus,the product formed is cyclopropane.
