JEE Main 2024 · 1 February · morning · Single correct · +4 / −1
Given below are two statements :
Statement (I) : Aminobenzene and aniline are same organic compounds.
Statement (II) : Aminobenzene and aniline are different organic compounds.
In the light of the above statements, choose the most appropriate answer from the options given below :
- (a) Both Statement I and Statement II are correct
- (b) Statement I is incorrect but Statement II is correct
- (c) Statement I is correct but Statement II is incorrect
- (d) Both Statement I and Statement II are incorrect
Answer and solution

Solution
Chemistry ma’am · 4 steps
Aniline is just the common name; aminobenzene is the name built from its structure. Same molecule.
- Read the name. Aminobenzene means a benzene ring carrying one amino group, -NH₂. That is C₆H₅NH₂.
- Aniline. Aniline is the common (trivial) name of C₆H₅NH₂, the simplest aromatic amine. In IUPAC naming it is called benzenamine.
- Compare. Aniline, aminobenzene and benzenamine are three names for one compound. The formula and structure are identical, so Statement I is correct and Statement II is incorrect.
- So. The answer is (c): Statement I is correct but Statement II is incorrect.
The idea to keep. One compound can carry a common name, a substitutive name and an IUPAC name. Draw the structure from each name, and if the drawings match, it is the same compound.
