Description: Polyhalogen compounds are carbon compounds containing more than one halogen atom. It has different types of compounds which have different uses.

Question

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) $C_{6} H_{5} {CH}_{2} Cl$

Accepted Answer

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) ${CCl}_{2} F_{2}$

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) $C_{6} H_{5} {CH}_{2} Cl$
