Choose the incorrect statement from the following.
- A \(\mathrm{CH}_2 \mathrm{Cl}_2\) is widely used as a propellant in aerosols.
- B Freon 1, 2 is manufactured from trichloromethane by Swartz reaction
- C Antiseptic property of Iodoform is due to the liberation of \(\mathrm{I}_2\) when it comes in contact with skin
- D DDT was widely used because of its effectiveness against mosquitos that spread malaria
Answer & Solution
Correct Answer
(B) Freon 1, 2 is manufactured from trichloromethane by Swartz reaction
Step-by-step Solution
Detailed explanation
Dichloromethane (\(\mathrm{CH}_2 \mathrm{Cl}_2\)) is used as a solvent, a paint remover, as a propellant in aerosols, and as a process solvent in the manufacture of drugs. However, Freon 12 (\(\mathrm{CCl}_2 \mathrm{F}_2\)) is manufactured from tetrachloromethane…
