Question:
The method by which aniline cannot be prepared is
The method by which aniline cannot be prepared is
Updated On: May 15, 2024
- Nitration of benzene followed by reduction with Sn and con HCI
- Degradation of benzamide with bromine in alkaline solution
- Reduction of nitrobenzene with $H_2 / Pd$ is ethanol
- Potassium salt of phthalimide treated with chlorgbenzene followed by the hydrolysis with aqueous NaOH solution
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Gabriel phthalimide synthesis not preferred for preparing aniline because amine formation involves
nucleophilic substitution of alkyl halides by the anion formed by phthalimide. But aryl halides do not
undergo nucleophilic substitution.
nucleophilic substitution of alkyl halides by the anion formed by phthalimide. But aryl halides do not
undergo nucleophilic substitution.

Concepts Used:
Nitrogen
- Nitrogen is the 7th element of the periodic table between carbon and oxygen.
- It’s a crucial part of amino acids.
- Around 80% of the Earth’s atmosphere comprises nitrogen gas.
- It is odorless and colorless in nature, mostly diatomic non-metal gas.
- Since it has 5 electrons in its outermost shell, most of its compounds are trivalent.
- It is a combination of all living tissues. Since it is a component of DNA and part of a genetic code, it is a necessary element of life.
- It is found in nitrates and further nitrites in soil and water.
- The nitrogen cycle comprises all these substances and is interconnected. Industrial companies emit nitrogen enormously, increasing nitrite and nitrate content in the ground and water, being the repercussion of reactions in the nitrogen cycle.
