Aniline is diazotized and the diazonium salt hydrolysed to yield phenol which is brominated to produce C6H2(Br3)OH. Calculate the mass of the final product obtained from 9.3 g of aniline if the yield in the two steps is 45% and 70% (Atomic mass of Br = 80) ?

Mol of C6H5OH formed =9.39.3×45100=0.045
Mol of C6H2(Br3)OH=0.045×70100=0.0315
Mass of C6H2(Br3)OH formed =0.0315×331=10.43g
