101.	Which of the following is a reduction inhibitor in amminating reagents?(a) KClO3(b) H2SO4(c) Zinc(d) None of the mentionedThe question was asked in semester exam.This is a very interesting question from Amination by Ammonolysis Classification in division Amination by Ammonolysis of Unit Processes
Answer» Correct ANSWER is (a) KClO3 Explanation: REDUCTION inhibitors, such as KCIO3, used in the AMINATION of chloroanthraquinone.

102.	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 mentionedI had been asked this question by my college professor while I was bunking the class.This intriguing question comes from Amination by Ammonolysis Classification in section Amination by Ammonolysis of Unit Processes
Answer» The correct choice is (a) Handling The EXPLANATION is: 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.

103.	How is the ionizing power of liquid ammonia?(a) Large(b) Small(c) Very small(d) None of the mentionedThis question was posed to me in final exam.My doubt stems from Amination by Ammonolysis Classification in chapter Amination by Ammonolysis of Unit Processes
Answer» RIGHT CHOICE is (a) Large To elaborate: The ionizing power of liquid AMMONIA is due largely to the high speed at which the ions of dissolved electrolytes MOVE in this solvent.

104.	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 mentionedThe question was posed to me in an online interview.This intriguing question originated from Amination by Ammonolysis Classification topic in section Amination by Ammonolysis of Unit Processes
Answer» Correct answer is (d) All of the mentioned Easy 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.

105.	Liquid ammonia resembles water in its general physical and chemical properties.(a) True(b) FalseThis question was addressed to me during a job interview.The above asked question is from Amination by Ammonolysis Classification in chapter Amination by Ammonolysis of Unit Processes
Answer» The correct OPTION is (a) True To EXPLAIN I would say: LIQUID ammonia resembles water in its general physical and chemical properties, both ammonia and water are associated liquids.

106.	In which reaction does nascent or recycled amines compete with ammonia?(a) Dehydration reaction(b) Double decomposition(c) Simple addition(d) Multiple activityThis question was addressed to me in an interview.The query is from Amination by Ammonolysis Classification topic in section Amination by Ammonolysis of Unit Processes
Answer» Correct choice is (d) Multiple activity Easiest 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.

107.	What happens during ‘ Double decomposition’?(a) NH3 splits for reaction(b) Exchange of molecules(c) All of the mentioned(d) None of the mentionedThis question was addressed to me by my school teacher while I was bunking the class.The doubt is from Amination by Ammonolysis Classification in portion Amination by Ammonolysis of Unit Processes
Answer» The correct answer is (a) NH3 splits for reaction Easiest 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.

108.	Amination by ammonolysis is a process of formation of what?(a) Phenols(b) Amines(c) Alcohols(d) HalogensThis question was addressed to me at a job interview.I need to ask this question from Amination by Ammonolysis Classification topic in chapter Amination by Ammonolysis of Unit Processes
Answer» Right OPTION is (B) Amines Explanation: Amination by AMMONOLYSIS is the process of FORMING amines by the action of AMMONIA.

109.	What do we call ammonia-hydrogen mixture?(a) Hydroammonolysis(b) Ammonolysis(c) Nitroammonolysis(d) None of the mentionedThe question was posed to me in an interview for job.Question is taken from Amination by Ammonolysis Classification topic in section Amination by Ammonolysis of Unit Processes
Answer» Right OPTION is (a) Hydroammonolysis To explain I would SAY: Hydroammonolysis is a process in which ammonia-hydrogen mixtures is MADE in the presence of a hydrogenation CATALYST.
