Question

Assertion (A): Nitration of benzene with nitric acid requires the use of concentrated sulphuric acid.

Reason (R): The mixture of concentrated sulphuric acid and concentrated nitric acid produces the electrophile, $N{0}_2^{+}$

• A. Both A and R are correct but R is not the correct explanation of A.
• B. Both A and R are not correct.
• C. Both A and R are correct and R is the correct explanation of A.
• D. A is not correct but R is correct.

Answer 1

The correct option is C Both A and R are correct and R is the correct explanation of A.

Solution:

Nitration of benzene-



The above reaction explains the addition of nitro groups on benzene. It is an electrophilic substitution reaction of benzene where $N{0}_2^{+}$ acts as the electrophilie.

Both A and R are correct and R is the correct explanation of A. Option (A) is correct.
