Question

Freon R-22 is.
A. $CHCl{F_2}$
B. $CC{l_2}{F_2}$
C. $C{H_3}Cl$
D. $C{H_2}C{l_2}$

Answer 1

Hint: In order to find the chemical formula of the compound one must have to know the chemical name of the compound. Freon is a chlorofluorocarbon and which is important for polyhalogens. We have to remember that the Freon is utilized for various halocarbon items. They are steady, nonflammable, low harmfulness gases or fluids which have commonly been utilized as refrigerants and as airborne fuels.

Complete step by step answer: As we know that the Dichlorodifluoromethane or difluorodichloromethane is a hydro chlorofluorocarbon (HCFC). This dreary gas is also called\[HCFC - 22\] or \[R - 22\] or \[CHCl{F_2}\]. If hydrogens in the methane molecule are replaced by two chloro and two fluorine atoms we get a Freon molecule.
We can draw the structure of Freon-22 as,

It is generally utilized as a force and refrigerant. These applications are being eliminated in created nations because of the compound's ozone consumption potential (ODP) and high an unnatural weather change potential albeit worldwide utilization of R-22 keeps on expanding in light of appeal in creating countries. R-22 is a flexible middle of the road in mechanical organofluorine science, for example as an antecedent to tetrafluoroethylene.
In case of option B, the name of the given compound $CC{l_2}{F_2}$ is known as Feron-12. Therefore, option B is incorrect.
In case of option C, the name of the given compound $C{H_3}Cl$ is methyl chloride. Therefore, the option C is incorrect.
In case of option D, the name of the given compound $C{H_2}C{l_2}$ is dichloromethane. Therefore, the option D is incorrect. So, the correct answer is “Option A”.

Note:
We must remember that the Freon incorporates the chlorofluorocarbons (CFCs) that cause ozone consumption and HCFCs, (for example, Chlorodifluoromethane). Not all refrigerants of this sort are named as "Freon" since Freon is a brand name for the refrigerants R-12, R-13B1, R-22, R-410A, R-502, and R-503. The expression "Freon" is a typical descriptor or restrictive eponym (like a nonexclusive brand name) like "Xerox" , "iced drops" or "Kleenex". It is normally utilized when alluding to any fluorocarbon refrigerants. The gas-based type of Freon is known to emanate a solid substance smell similar to that of CH3)2CO, or nail clean remover.
