A Grignard synthesis begins with 6.00 g of bromobenzene and ends with 3.94 g benzoic acid. What is the percent yield of the benzoic acid

Sagot :

The percentage yield of the benzoic acid is mathematically given as
P= 84.56 %

What is the percentage yield of the benzoic acid?

Question Parameters:

A Grignard synthesis begins with 6.00 g

and ends with 3.94 g benzoic acid.

Generally, if 157 g of bromobenzene produced = 122 g of benzoic acid

Hence,6 g of bromobenzene will produce

X== (122 / 157 ) * 6

X= 4.66 g

Since the experimental yield of benzoic acid = 3.94 g

Therefore the Percentage yield

P = 3.94 / 4.66  * 100

P= 84.56 %
