Arenediazonium salts are more stable than alkanediazonium salts due to dispersal fo the positive charge on the benzene ring. Obviously, electron-donating groups favour diazotisation by retarding the decomposition of diazonium salts to phenyl cation. The high reactivity of arenediazonium salts is due to the excellent leaving ability of the diazo group as N_(2) gas. Q. Which of the following arylamines undergoes diazotisation most readily?

1.	Arenediazonium salts are more stable than alkanediazonium salts due to dispersal fo the positive charge on the benzene ring. Obviously, electron-donating groups favour diazotisation by retarding the decomposition of diazonium salts to phenyl cation. The high reactivity of arenediazonium salts is due to the excellent leaving ability of the diazo group as N_(2) gas. Q. Which of the following arylamines undergoes diazotisation most readily?
Answer» SOLUTION :The diazonium salt formed is STABILIZED by the POWERFUL +R-effet of the `OCH_(3)` group.
