When chloral hydrate is distilled with sodium hydroxide solution, it forms:
Give the uses of freon 12, DDT, carbon tetrachloride and iodoform.
The uses of various compounds ar given below.
Freon $$12 $$
$$1)$$ It is used as a refrigerant in refrigerators and air conditioners.
$$2)$$ It is used in aerosol spray propellants such as body sprays, hair sprays etc.
DDT :
$$1)$$ It is used as an insecticide.
$$2)$$ It is effective against mosquitoes and lice.
Carbon tetrachloride:
$$1)$$ It is used in manufacturing refrigerants and propellants for aerosol cans.
$$2)$$ It is used as feedstock in the synthesis of chlorofluorocarbons and other chemicals.
$$3)$$ It is used as a solvent in the manufacture of pharmaceutical products.
$$4)$$ Till $$1960$$'s, it was used as a cleaning fluid, a degreasing agent and a fire extinguisher.
Iodoform.:
It was used as an antiseptic as it liberates free iodine when it comes in contact with the skin.
When chloral hydrate is distilled with sodium hydroxide solution, it forms:
In which of the following reactions chlorine acts an oxidising agent. i) $$CH_3CH_2OH+Cl_2\rightarrow CH_3CHO+HCl$$ ii) $$CH_3CHO+Cl_2\rightarrow CCl_3CHO+HCl$$ iii) $$CH_4+Cl\xrightarrow[]{hv} CH_3Cl+HCl$$ The correct answer is :
