The cleavage of C-O bond in ether takes place under drastic conditions with excess of hydrogen halides.
When one of the alkyl groups is a tertiary group, the halide formed is a tertiary halide.
When one of the alkyl groups is a tertiary group, the halide formed is a tertiary halide.
Mechanism:
(i) protonation of tert-butyl methyl ether-
(i) protonation of tert-butyl methyl ether-
(ii)
In the second step, the departure of the learning group yields a tertiary i.e. a stable carbocation so the reaction proceeds through an SN’ mechanism.
(iii)
(iii)
So, The correct option is c.

Assertion: With HI at 373 K, ter-butyl methyl ether gives ter-butyl iodide and methanol.
Reason: The reaction occurs by SN2 mechanism.
The correct answer is option 'C', which states that the Assertion is correct but the Reason is incorrect.
Explanation:
Assertion: With HI at 373 K, ter-butyl methyl ether gives ter-butyl iodide and methanol.
This statement is correct. Ter-butyl methyl ether (MTBE) can undergo a reaction with hydrogen iodide (HI) to form ter-butyl iodide and methanol. This reaction is an example of a nucleophilic substitution reaction.
Reason: The reaction occurs by SN2 mechanism.
This statement is incorrect. The reaction between ter-butyl methyl ether and hydrogen iodide occurs through an SN1 (substitution nucleophilic unimolecular) mechanism rather than an SN2 (substitution nucleophilic bimolecular) mechanism.
In an SN1 mechanism, the reaction proceeds in two steps. First, the ter-butyl methyl ether molecule undergoes ionization to form a ter-butyl carbocation and methanol. The carbocation is then attacked by the iodide ion, resulting in the formation of ter-butyl iodide.
The SN2 mechanism, on the other hand, involves a one-step process where the nucleophile (iodide ion) directly attacks the substrate (ter-butyl methyl ether) and displaces the leaving group (methanol) in a concerted manner.
In the given reaction, the presence of HI as a strong acid promotes the ionization of ter-butyl methyl ether, leading to the formation of a carbocation intermediate. This intermediate is then attacked by the iodide ion, resulting in the formation of ter-butyl iodide and methanol.
Therefore, the Assertion is correct as the reaction does occur, but the Reason is incorrect as the reaction proceeds via an SN1 mechanism and not an SN2 mechanism.
Reason: The reaction occurs by SN2 mechanism.
The correct answer is option 'C', which states that the Assertion is correct but the Reason is incorrect.
