Question

Synthesis of Benzanilide

procedure

--> reaction

■Calculations

–Theoretical Yield

–Practical Yield

–Percentage Yield

■Conclusion

Answer 1

When Aniline reacts with benzoylchloride in the presence of NaOH then it gave benzanilide with some NaCl and water.

Reaction:

$C_6H_5NH_2+C_6H_5COCl\Rightarrow C_6H_5NHCOC_6H_5+NaCl+H_2O$

$\Rightarrow$ The theoretical yield of Benzanilide is 100% .

$\Rightarrow$ The practical yield of Benzanilide is observed in lab and it differs from measurment to measurment.

$\Rightarrow$ The formula of Percentage yield is $=\dfrac{Practical Yield}{Theoretical Yield}$

$\Rightarrow$ Conclusion$\rightarrow$ It is grayish to yellow green powder which is insoluble in water.It is stored below 30 degree celcius.
