Solution
NaNO2/HCl converts primary amines to diazonium salts, which can lose N2 to form carbocations. The carbocation stability determines if rearrangement occurs.
Compounds I and III both generate the same secondary carbocation. I directly forms . III forms a primary carbocation that rearranges via hydride shift to the same stable secondary carbocation.
Final Answer: I and III
