In the electrophilic Aromatic
Substitution to yield 4-
Bromoacetanilide. Calculate the
following:
1. Yield of recrystallized 4-bromoacetanilide
2. % Yield of 4-bromoacetanilide for the
purification step (recrystallized yield/
crude yield) x 100
3. % Yield for the bromination reaction =
%3D
(recrystallized yield/theoretical yield) x 100
The given amounts:
Acetanilide used: 103 mg
Crude used for recrystallization
product: 115 mg
Actual yield 4-bromoacetanilide:
135 mg
Theoretical yield 4-
bromoacetanilide: 0.163 g
Yield purified product: 85 mg
