AIIMS 2019 Chemistry Gabriel Phthalimide Synthesis MCQ Question

In Gabriel phthalimide synthesis, the formation of tertiary butyl amine is hindered because the reaction proceeds via an elimination mechanism rather than a substitution mechanism, specifically due to steric hindrance and the stability of the resulting alkene. This reaction does not follow the Sₙ1 mechanism, which typically involves the formation of a stable carbocation; instead, the bulky tertiary butyl group favors elimination to form an alkene. Other options are not relevant as they do not pertain to the mechanisms or outcomes of the Gabriel synthesis process. Understanding these mechanisms is crucial for predicting reaction pathways in organic chemistry.
