Assertion : \(\mathrm{C}_{2} \mathrm{H}_{5} \mathrm{Br}\) reacts with alcoholic solution of \(\mathrm{AgNO}_{2}\) to form nitroethane as the major product. Reason : \(\mathrm{NO}_{2}\) is an ambidient ion.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
Explanation:
The covalent compound silver nitrite \(\left(\mathrm{AgNO}_{2}\right)\) contains a nitrogen atom with a lone pair, allowing it to act as a donor in the substitution reaction, leading to the synthesis of nitroethane by replacing the bromine atom. Thus, option (2) is correct.

The rate determining step for the prepration of nitrobenzene from benzene is.
1 Removal of \(\stackrel{+}{\mathrm{N}} \mathrm{O}_{2}\)
2 Removal of \(\mathrm{H}^{+}\)
3 Formation of \(\stackrel{+}{\mathrm{N}} \mathrm{O}_{2}\)
4 Formation of \(\stackrel{+}{\mathrm{N}} \mathrm{O}_{3}\)
Explanation:
Formation of nitronium ion is rate determining step.

Assertion : Nitration of benzene and hexadeuterobenzene occur exactly at the same rate. Reason : The cleavage of \(\mathrm{C}-\mathrm{H}\) bond is not the rate determining step of the reaction.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
Explanation:
The identical rate of nitration in benzene and hexadeuterobenzene is a result of the primary kinetic isotope effect, where the substitution of hydrogen with deuterium does not significantly impact the reaction rate as cleavage of \(\mathrm{C}-\mathrm{H}\) bond is not the rate determining step. So option (1) is correct.
