Match the following: (a) Allyl chloride (1) CH 2 = CHCl (b) Benzyl chloride (2) CCl 2 F 2 (c) Vinyl chloride (3) CH 2 - CHCH 2 Cl (d) Freon (4) C 6 H 5 CH 2 Cl

Allyl chloride is an Allylic halide. Allylic halides are the compounds in which the halogen atom is bonded to an sp 3 - hybridised carbon atom adjacent to a carbon-carbon double bond ( C = C ) i.e. to an allylic carbon. The structure of Allyl chloride is CH 2 = CHCH 2 Cl . Benzyl chloride is a Benzylic halide with the chemical formula C 6 H 5 CH 2 Cl . These are the compounds in which the halogen atom is bonded to an sp 3 - hybridised carbon atom attached to an aromatic ring. Vinyl chloride is an example of Vinylic halide with the chemical formula CH 2 = CHCl . These are the compounds in which the halogen atom is bonded to a sp 2 - hybridised carbon atom of a carbon-carbon double bond ( C = C ) . The chlorofluorocarbon compounds of methane and ethane are collectively known as freons. They are extremely stable, unreactive, non-toxic, non-corrosive and easily liquefiable gases. Freon 12 CCl 2 F 2 is one of the most common freons in industrial use. It is manufactured from tetrachloromethane by Swarts reaction. (a) Allyl chloride (3) CH 2 - CHCH 2 Cl (b) Benzyl chloride (4) C 6 H 5 CH 2 Cl (c) Vinyl chloride (1) CH 2 = CHCl (d) Freon (2) CCl 2 F 2
