AIIMS 2018 Chemistry IUPAC Nomenclature MCQ Question
Write IUPAC name of following

2-chloro-1-methoxy-4-nitrobenzene
2-chloro-4-nitro anisole
3-chloro-4-methoxy-1-nitrobenzene
1-chloro-2-methoxy-5-nitrobenzene
Correct Answer
Detailed Explanation
The IUPAC name "Chloro-1-methoxy-4-nitrobenzene" indicates a benzene ring with a chloro group at position 1, a methoxy group (-OCH₃) at position 1, and a nitro group (-NO₂) at position 4. This naming follows the standard IUPAC conventions for substituents on aromatic compounds, where substituents are listed in alphabetical order, and the positions are numbered to give the lowest possible numbers to the substituents. Other options are incorrect as they do not accurately reflect the functional groups and their respective positions on the benzene ring as described in the question.
