Consider the above reactions, the product \( \mathrm{A} \) and product \( \mathrm{B} \) respectively are:

Among the following structures, which will show the most stable enamine formation? (Where Me is \( \mathrm{-CH_3} \))

The correct stability order of the following diazonium salt is

Given below are two statements:
Statement -I : In Hofmann degradation reaction, the migration of only an alkyl group takes place from carbonyl of the amide to the nitrogen atom.
Statement -II : The group is migrated in Hofmann degradation reaction to electron deficient atom.

An organic compound ‘A’ on reaction with \( \mathrm{NH_3} \) followed by heating gives compound B. Which on further strong heating gives compound C \( \mathrm{(C_8H_5NO_2)} \). Compound C on sequential reaction with ethanolic \( \mathrm{KOH} \), alkyl chloride and hydrolysis with alkali gives a primary amine. The compound A is:

Given below are two statements : one is labelled as Assertion A and the other is labelled as Reason R
Assertion A: Aniline on nitration yields ortho, meta & para nitro derivatives of aniline
Reason R : Nitrating mixture is a strong acidic mixture
In the light of the above statements, choose the correct answer from the options given below.

. Match List -I with List-II

Choose the correct answer from the options given below:

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A): Experimental reaction of \( \mathrm{CH_3Cl} \) with aniline and anhydrous \( \mathrm{AlCl_3} \) does not give o and p-methylaniline.
Reason (R): The \( -\mathrm{NH_2} \) group of aniline becomes deactivating because of salt formation with anhydrous \( \mathrm{AlCl_3} \) and hence yields m-methyl aniline as the product.
In the light of the above statements, choose the most appropriate answer from the options given below:

The Hinsberg reagent is:

10.

Identify the major product formed in the following sequence of reactions:

11.

Which among the following represent reagent ‘A’?

12.

An organic compound ‘A’ contains nitrogen and chlorine. It dissolves readily in water to give a solution that turns litmus red. Titration of compound ‘A’ with standard base indicates that the molecular weight of ‘A’ is \(131 \pm 2\). When a sample of ‘A’ is treated with aq. \( \mathrm{NaOH} \), a liquid separate which contains \( \text{N} \) but not \( \text{Cl} \). Treatment of the obtained liquid with nitrous acid followed by phenol gives orange precipitate. The compound ‘A’ is:
