Some of the physical property are as follows.
Some of the chemical property are as follows.
1. Oxidation reaction.
Chloroform is oxidised in the air in presence of sunlight to form a poisonous compound called phosgene.
Chloroform is stored in a dark brown bottle with a tight lid so as to prevent the formation of poisonous phosgene.
Chloroform containing bottle is often supplied with a small amount of ethanol since it converts phosgene into diethyl carbonate which is non-poisonous.
Chloroform is reduced to dichloro methane in acidic and neutral medium respectively.
Chloroform on boiling with aqueous KOH hydrolyzed to form potassium formate.
Chloroform on further chlorination gives carbon tetrachloride.
5. Action with nitric acid.
Chloroform on heating with concentrated nitric acid forms chloropicrin which is used as an insecticide and war gas.
6. Action with silver powder.
7. Reaction with Phenol. (Reimer -Tiemann reaction).
When phenol is heated with chloroform and aqueous alkaline at temperature 60-700C, O-hydroxy benzaldehyde (Salicylaldehyde) is formed as the chief organic product. This reaction is termed as Riemer-Tiemann reaction.
8. Reaction with the primary amine.
Chloroform produces an offensive smelling carbylamines or isocyanide when warmed with the Primary amine (R-NH2-aliphatic or aromatic) in presence of an alkali. This reaction is known as carbylamines reaction.
A haloalkane P reacts with aq. KOH to give Q. The compound Q on oxidation with K2Cr2O/H+ give R and R undergo Clemmensen reduction to produce S. The compound P reacts with sodium in presence of dry ether to form 2,3 dimethylbutane, Write chemical reactions involved and identify P,Q,R and S.
Let identify P at first reacts with sodium metal in the presence of dry ether to give 2,3 dimethylbutane so P should be 2- Haloproparopane.
