Question

Read the assertion and reason carefully to mark the correct option out of the options given below:
Assertion: Nitrating mixture used for carrying our nitration of benzene consists of $conc.HN{O}_3+conc.H_{2}S{O}_4.$

Reason :In presence of$H_{2}S{O}_4,HN{O}_3$ acts as a base and produces$N{O}_2^{+}$ions.

• A. If both assertion and reason are true and the reason is the correct explanation of the assertion.
• B. If both assertion and reason are true but reason is not the correct explanation of the assertion.
• C. If assertion is true but reason is false.
• D. If the assertion and reason both are false.

Answer 1

The correct option is A If both assertion and reason are true and the reason is the correct explanation of the assertion.

$HN{O}_3+2H_{2}S{O}_4\leftrightharpoons 2HS{O}_4^{-}+N{O}_2^{+}+H_3{O}^{+}$
