(a)
Interpretation:
The curved-arrow mechanism for the given reaction is to be stated. The role of weak acid ammonium chloride is also to be stated.
Concept introduction:
The nitrogen groups are not good leaving groups in the form of negatively charged nitrogen because of stronger basic nature. Even if the ring strain is removed still that is not enough for nitrogen to leave as negative ion. Therefore, acid is used to protonate nitrogen before its elimination so that it will leave as neutral nitrogen.
(b)
Interpretation:
An explanation as to why the reaction of aziridine requires a weak acid is to be stated.
Concept introduction:
The nitrogen groups are not good leaving groups in the form of negatively charged nitrogen because of stronger basic nature. Even if the ring strain is removed still that is not enough for nitrogen to leave as negative ion. Therefore, acid is used to protonate nitrogen before its elimination so that it will leave as neutral nitrogen.
(b)
Interpretation:
The suggestion of using a dilute solution of strong acid
