List of top Chemistry Questions on Organic Compounds Containing Nitrogen

The activation energy for the reaction X \(\rightarrow\) Y is 150 kJ mol\(^{-1}\). The change in enthalpy for the above reaction is -135 kJ mol\(^{-1}\). Then the activation energy for Y \(\rightarrow\) X is

Consider the following set of reactions.
$\text{C}_6\text{H}_5\text{CN} \xrightarrow{\text{B}} \text{Y} (\text{reacts with } 2,4\text{-DNP}) \xrightarrow{\text{A}} \text{X} (\text{dissolves in dil. } \text{HCl})$
What are A and B respectively?

Identify the product 'Y' in the given sequence of reactions. (Chlorobenzene reacts with Conc. HNO$_3$ and Conc. H$_2$SO$_4$ to give X (Major). X then reacts with (i) NaOH, 443 K and (ii) H$^+$ to give Y.)

The correct statements about the products B and C in the given reactions are (Ethanol reacts with HCl/Anhy ZnCl$_2$ to give A. A reacts with ethanolic AgCN to give B (Minor) and C (Major)). I. B and C are functional isomers II. With H$_2$|Catalyst B gives 1$^\circ$ amine and C gives 2$^\circ$ amine III. B on acid hydrolysis gives formic acid and C gives C$_3$H$_6$O$_2$ IV. C forms isocyanate with HgO

The reagent which is used to distinguish primary, secondary and tertiary amines from the mixture is

What is the product 'Z' in the following reaction sequence?

What is the formula of urea?

Aniline does not undergo Friedel-Crafts reaction because 1.(A) It forms salt with the Lewis acid catalyst, AlCl₃.
2. (B) Nitrogen of aniline acquires negative charge.
3. (C) Nitrogen of aniline acquires positive charge.
4. (D) Nitrogen acts as a strong deactivating group in the further reaction.
