Aniline is diazotized and the diazonium salt hydrolysed to yield phenol which is brominated to produce C_(6)H_(2)(Br_(3))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)

Answer»

1.04 g<BR>10.43 g
14.89 g
23.17 g

Solution :`C_(6)H_(5)NH_(2) overset("45% yield")to C_(6)H_(5)OH overset("70% yield")to C_(6)H_(2)(Br_(3))OH`
Mol of `C_(6)H_(5)OH "formed"=(9.3)/(93) XX (45)/(100)=0.045`
Mol of `C_(6)H_(2)(Br_(3))OH=0.045 xx (70)/(100)=0.0315`
Mass of `C_(6)H_(2)(Br_(3))OH "formed" =0.0315 xx 331=10.43 g`
