Solution
This reaction is known as Finkelstein reaction and this is a halide exchange SN2 reaction.
Through this reaction we can exchange one alkyl halide into another alkyl halide by using metal halide salt.
Hence, major product of the reaction is Propyl Iodide.
Elimination reaction takes place in presence of alcoholic KOH as follows:
Major product of the reaction is 2-methylprop-1-ene.
In presence of aq. NaOH/KOH, substitution reaction takes place as follows:
Hence, major product of the reaction is butan-2-ol.
Nucleophilic substitution reaction takes place as follows:.
Hence, major product of the reaction is propanenitrile.
This is Williamson ether synthesis reaction with SN2 mechanism.
Hence, major product of the reaction is ethoxy benzene.
The method of the reaction is SNi type. In this reaction the alcohol reacts with thionyl chloride to give propyl chloride. There is retention of configuration in SNi reactions and the leaving groups are gaseous species.
Hence, major product of the reaction is propyl chloride.
In anti markovnikov addition reaction the negative part of the HBr i.e. bromide ion will associate with the carbon having more number of hydrogen atoms.
Hence, major product of the reaction is butyl bromide
In Markovnikov addition reaction the negative part of the HBr i.e. bromide ion will associate with the carbon having less number of hydrogen atoms.
Hence, major product of the reaction is 2-bromo-2-methylbutane.
Through this reaction we can exchange one alkyl halide into another alkyl halide by using metal halide salt.
