Question

In the bromination reaction of ​trans​-cinnamic acid, a student started with 300 mg oftrans​-cinnamic acid and excess bromine. They then obtained 240 mg of pure2,3-dibromo-3-phenylpropanoic acid. What is the % yield of pure2,3-dibromo-3-phenylpropanoic acid?

Answer 1

The percentage yield is= 80%

Step-by-step explanation:

% yield= actual yield/theoretical yield ×100

From The question

Actual yield= 240mg

Theoretical yield= 300mg

%yield= 240/300×100= 80%
