Problem- a) Decide which is more stable: an aryldiazonium cation, or a cyclohexyldiazonium cation? Use resonance structures to justify your answer.
b) Upon heating to temperatures above 50oC, aryldiazonium salts decompose and evolve nitrogen gas.
Please illustrate a mechanism for the decomposition of an aryldiazonium cation as well as briefly explain why one of the decomposition products formed is so reactive.
