FAQs on JEE Main 2025-26 Mock Test: Organic Compounds Containing Nitrogen
1. What are organic compounds containing nitrogen?
Organic compounds containing nitrogen are chemical substances made up of carbon, hydrogen, and at least one nitrogen atom. These compounds include amines, amides, nitro compounds, cyanides, and isocyanides. They play important roles in both biological systems and industrial applications.
2. What are the main classes of nitrogen-containing organic compounds?
Main classes of organic compounds containing nitrogen include: Amines, Amides, Nitro compounds, Cyanides (Nitriles), and Isocyanides. Each class differs by the functional group containing nitrogen and has unique chemical properties.
3. What is an amine? Briefly classify amines.
Amines are organic derivatives of ammonia (NH₃) where one or more hydrogen atoms are replaced by alkyl or aryl groups. Classification of amines:
- Primary amines (1°): One hydrogen replaced (e.g., CH₃NH₂).
- Secondary amines (2°): Two hydrogens replaced (e.g., (CH₃)₂NH).
- Tertiary amines (3°): All three hydrogens replaced (e.g., (CH₃)₃N).
4. How do you prepare primary amines from alkyl halides?
Primary amines can be prepared from alkyl halides by reacting them with excess ammonia (NH₃) in an ethanolic medium through a process called the ammonolysis of alkyl halides. The reaction produces a primary amine and a halide salt.
5. What is the Hofmann degradation reaction?
The Hofmann degradation (Hofmann rearrangement) is a chemical reaction in which a primary amide reacts with bromine and an alkali to produce a primary amine with one less carbon atom than the original amide. This reaction is useful in organic synthesis for chain-shortening.
6. What are some uses of organic compounds containing nitrogen?
Nitrogen-containing organic compounds are widely used in daily life and industry, such as:
- Amines: Medicines, dyes, explosives
- Amides: Pharmaceuticals, plastics, fibers (Nylon)
- Nitro compounds: Explosives (TNT), solvents
- Cyanides: Industrial extraction of gold and silver
7. How are nitro compounds prepared in the laboratory?
Nitro compounds are prepared by the process of nitration, which involves reacting an organic substrate (like benzene) with concentrated nitric acid and sulfuric acid to introduce the nitro group (-NO₂) into the molecule.
8. What test is used to detect amines in organic compounds?
Amines are commonly detected by the Carbylamine reaction (Isocyanide test). In this test, a primary amine reacts with chloroform and alcoholic KOH to produce a foul-smelling isocyanide, indicating the presence of a primary amine.
9. What is the difference between cyanides and isocyanides?
Cyanides have the functional group (-C≡N), while isocyanides have the group (-N≡C). The main difference is the bonding of the nitrogen atom to the carbon chain. Cyanides are generally less toxic than isocyanides and have very different chemical properties.
10. What are the basic physical properties of amines?
Amines are generally colorless, volatile liquids or gases with a strong characteristic odor. Lower amines are soluble in water due to hydrogen bonding, while higher ones are less soluble and have higher boiling points because of intermolecular hydrogen bonds.
11. Which functional groups contain nitrogen?
Functional groups containing nitrogen include:
- Amino group (-NH₂)
- Amide group (-CONH₂)
- Nitro group (-NO₂)
- Cyanide group (-CN)
- Isocyanide group (-NC)
12. Why are primary amines more reactive than secondary and tertiary amines?
Primary amines are more reactive than secondary and tertiary amines due to the presence of two hydrogen atoms attached to the nitrogen atom. This makes them more available for reactions like hydrogen bonding and nucleophilic substitution, and also more readily detected in chemical tests such as the Carbylamine reaction.
