In an experiment a student allowed benzene C6H6+ TO REACT WITH EXCESS BROMINE BR2+ In an attempt to prepare bromobenzene C6H5Br. This reaction also produced as a by-product, dibromobenzene, C6H4Br2+ On the basis of the equation.
C6H6 + Br2 -> c6h5Br + H Br
a) What is the maximum amount of C6H5Br that the student could have hoped to obtain from 15.0 g of benzene? (This is the theoretical yield.)
b) In this experiment the student obtained 2.50 C6H5Br2+. How much C6H6 was not converted to C6H5Br?
c) What is the student’s actual yield of C6H5Br?
d) Calculate the percentage yield for the reaction?
