The indicator that is obtained by coupling the diazonium salt of sulphanilic acid with N, N - dimethyl aniline is

How will you convert: Benzene to N,N-dimethyl aniline?

On subjecting mesityl oxide to the iodoform reaction, one of the products is the sodium salt of an organic acid. Which acid is obtained?

How many monochlorobutane is obtained on chlorination of n-butane ?

Arene diazonium salts are more stable than alkanediazonium salts due to dispersal of 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. Consider the following ions: The reactivity of these ions towards azo coupling reactions under similar conditions is
