Interpretation:
The classification of the formation of industrial preparation of methyl bromide from methanol by reaction with hydrogen bromide is to be done. The stepwise mechanism is to be written.
Concept introduction:
The reaction of methyl and primary alcohols with hydrogen halide mostly proceeds through SN2 mechanism.
The reaction of tertiary alcohol with hydrogen halide proceeds through SN1 mechanism.
The SN2 reaction is the bimolecular nucleophilic substitution reaction whose rate determining step involved two reactants (both electrophile and nucleophile).
The SN1 reaction is the unimolecular nucleophilic substitution reaction that means rate determining step involved only one reactant.
Formation of carbocation is the rate determining step in SN1 mechanism.
The nucleophile (halide ion) attacks on the electrophilic carbon from opposite side of hydroxyl group (i.e. backside attack) in SN2 mechanism.
The position of leaving group in reactant and that of nucleophile in the product are same in case of SN2 mechanism and it may be same or different in case of SN1 mechanism depending on the stability of carbocation.

The stationary phase is always more polar The mobile phase is always more polar It depends on our choices for both stationary and mobile phase Their polarity doesn't really matter so we never consider itarrow_forward
