Unit Processes Questions and Answers – Amination by Ammonolysis Classification

This set of Unit Processes Multiple Choice Questions & Answers (MCQs) focuses on “Amination by Ammonolysis Classification”.

1. Amination by ammonolysis is a process of formation of what?
a) Phenols
b) Amines
c) Alcohols
d) Halogens
View Answer

Answer: b
Explanation: Amination by ammonolysis is the process of forming amines by the action of ammonia.

2. What do we call ammonia-hydrogen mixture?
a) Hydroammonolysis
b) Ammonolysis
c) Nitroammonolysis
d) None of the mentioned
View Answer

Answer: a
Explanation: Hydroammonolysis is a process in which ammonia-hydrogen mixtures is made in the presence of a hydrogenation catalyst.

3. What happens during ‘ Double decomposition’?
a) NH3 splits for reaction
b) Exchange of molecules
c) All of the mentioned
d) None of the mentioned
View Answer

Answer: a
Explanation: During double decomposition, the NH3 molecule is split into -NH2 and -H fragments, the former becoming part of the newly formed amine, while the latter unites with the radical -Cl, -SOaR, -N02, etc., that is substituted.

4. In which reaction does nascent or recycled amines compete with ammonia?
a) Dehydration reaction
b) Double decomposition
c) Simple addition
d) Multiple activity
View Answer

Answer: d
Explanation: In multiple activity, the nascent or recycled amines compete with ammonia as a coreactant, resulting in the formation of secondary and tertiary amines by aminolysis.

5. What are/is the condition needed for the compound which is to be aminated?
a) Stability
b) Solubility
c) Effective catalyst
d) All of the mentioned
View Answer

Answer: d
Explanation: In selecting the particular aminating agent, consideration would be given to the temperature and pressure conditions normally required for a given type of compound, the type of catalyst that might be effective, the stability and solubility of the compound to be aminated.

6. Liquid ammonia resembles water in its general physical and chemical properties.
a) True
b) False
View Answer

Answer: a
Explanation: Liquid ammonia resembles water in its general physical and chemical properties, both ammonia and water are associated liquids.

7. How is the ionizing power of liquid ammonia?
a) Large
b) Small
c) Very small
d) None of the mentioned
View Answer

Answer: a
Explanation: The ionizing power of liquid ammonia is due largely to the high speed at which the ions of dissolved electrolytes move in this solvent.

8. Why is aq. NH3 used as an amminating agent in majority of cases?
a) Handling
b) More energy
c) Lower reaction rate
d) All of the mentioned
View Answer

Answer: a
Explanation: Aq. ammonia is used as an aminating agent in the greater amount and in the greatest number of cases. It has the advantage of greater convenience in handling and general applicability, and it readily dissolves sulfonic acids.

9. Which of the following is a reduction inhibitor in amminating reagents?
a) KClO3
b) H2SO4
c) Zinc
d) None of the mentioned
View Answer

Answer: a
Explanation: Reduction inhibitors, such as KCIO3, used in the amination of chloroanthraquinone.

10. The presence of which ion from ammonium hydroxide is responsible for formation of hydroxy compounds?
a) Ammonium ion
b) Hydroxy ion
c) Aniline ion
d) Benzene ion
View Answer

Answer: b
Explanation: The presence of hydroxyl ions from the dissociation of ammonium hydroxide, alkyl or aryl ammonium hydroxide, or water is responsible for the simultaneous formation of hydroxy compounds in certain reactions.
