Question

In the following reaction The % yield for reaction I is 60% and that of reaction II is 50%. The overall yield of the complete reaction is___% [nearest integer]

Accepted Answer

Correct answer: 30. (30) (I) Let initial moles of reactant taken = n Total moles obtained for benzene sulphonic acid (with % yield - 60%) = 0.6n (II) Moles of benzene sulphonic acid before reaction II = 0.6n Moles obtained for phenol (with % yield = 50%) = 0.6x0.5n=0.3n So over all % yield of complete reaction == 0.3 nn×1 0 0=3 0
