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 diazonium salts when boiled dil. H_(2)SO_(4) gives the corresponding phenol 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 diazonium salts when boiled dil. H_(2)SO_(4) gives the corresponding phenol most readily?
Answer» Solution :MeO group at m-position exerts -I-effect which TENDS to WEAKEN the `Ar-N_(2)^(+)` BOD thereby facilitating its DECOMPOSITION.
