Some Basic Concepts Of Chemistry Question 50
Question: 5 g of benzene on nitration gave 6.6 g of nitrobenzene. The theoretical yield of the nitrobenzene will be
Options:
A) 4.5 g
B) 5.6 g
C) 8.09 g
D) 6.6 g
Show Answer
Answer:
Correct Answer: C
Solution:
[c] $ \underset{78g}{\mathop{C _6H _6}},+HNO _3\to \underset{123g}{\mathop{C _6H _5NO _2}},+H _2O $ Now since 78g of benzene on nitration give = 123g nitrobenzene hence 5g of benzene on nitration give $ =\frac{123}{78}\times 5=7.88g $ nearest answer is [c] i.e. theoritical yield =7.88g
