CUET Chemistry Haloalkanes and Haloarenes: Important Points to Remember
There are following important points in this chapter of Haloalkanes and Haloarenes
CUET Chemistry: Alkyl Halide
Alkyl Halide [R-X] or [Halo Alkane] [Preparation]
Properties of Haloalkane / Alkyl Halide [Nucleophilic Substitution]
CUET Chemistry: Chemical Reactions of Haloalkanes
The reactions of haloalkanes may be divided into the following categories:
Alkyl halides undergoes nucleophilic substitution reaction by two mechanism SN1or SN2. SN1 forms carbocation in SN2 inversion of configuration occurs.
CUET Chemistry: Zaitseff Rule
Zaitsev (also pronounced as Saytzeff) who in 1875 formulated a rule which can be summarized as “in dehydrohalogenation reactions, the preferred product is that alkene which has the greater number of alkyl groups attached to the doubly bonded carbon atoms.”
CUET Chemistry: Haloarenes
Aryl Halide [Haloarenes] Preparation
Properties of Aryl halides
CUET Chemistry: Polyhalogen Compounds
Dichloromethane(Methylene chloride)
Solvent as a paint remover, metal cleaning and finishing solvent.
Methylene chloride harms the human central nervous system
Chloroform
Chloroform is slowly oxidised by air in the presence of light to an extremely poisonous gas, carbonyl chloride, also known as phosgene. It is therefore stored in closed dark coloured bottles completely filled so that air is kept out.
Freons:
The chlorofluorocarbon compounds of methane and ethane are collectively known as freons.
Freon 12 (CCl2F2) is one of the most common freons in industrial use. It is manufactured from tetrachloromethane by Swarts reaction.
DDT (p,p’-Dichlorodiphenyltrichloroethane)
The chemical stability of DDT and its fat solubility compounded the problem.
