JEE Main 2021 (Online) 18th March Evening Shift Chemistry - Aldehydes, Ketones and Carboxylic Acids Question 126 English
Consider the above reaction where 6.1 g of Benzoic acid is used to get 7.8 g of m-bromo benzoic acid. The percentage yield of the product is __________

(Round off to the Nearest Integer).

[Given : Atomic masses : C : 12.0 u, H : 1.0 u, O : 16.0 u, Br : 80.0 u]

Step-by-Step Verified Solution

Moles of Benzoic acid = 6.1122 = moles of m-bromobenzoic acid

So, weight of m-bromobenzoic acid = 6.1122 × 201 gm

= 10.05 gm

% yield = ActualweightTheoreticalweight×100

=7.810.05×100 = 77.61%
