AIIMS 2019 Chemistry SN1 Mechanism Assertion Reason Question

Type: Assertion Reason-conceptual-Medium-Class 12

Which will release NH3\text{NH}_3 on Reaction with NaOH\text{NaOH}

A

Hydrazoic acid (N3H\text{N}_3\text{H})

B

ethylenediamine tetra acetic acid

C

NH2OH\text{NH}_2 - \text{OH}

D

Triethylamine

Correct Answer

Option C

Detailed Explanation

The statement is incorrect regarding the formation of methyl alcohol; instead, the reaction produces tert-butyl bromide (C₄H₉Br) and not methyl alcohol (CH₃OH). The SN₁ mechanism involves the formation of a stable tertiary carbocation from tert-butyl methyl ether upon protonation, which then reacts with bromide ion to yield the bromide product. Options (A) and (B) incorrectly assert that both parts of the statement are true, while option (D) incorrectly claims both are false.
