}

• A. Methylchlorobenzene
• B. Toluene
• C. 1-Chloro-4-Methylbenzene
• D. 1-Methyl-4-Chlorobenzene

Hint:

For aromatic compounds with multiple substituents, the substituents should be numbered in such a way that the locants are as low as possible, with the substituents listed in alphabetical order.

Answer 1

The Correct Option is C

The compound contains both a methyl group and a chlorine atom attached to a benzene ring. The appropriate IUPAC name is 1-Chloro-4-Methylbenzene, where the numbering begins from the position of the chlorine atom and continues to the position of the methyl group. \bigskip Step 2: Therefore, the correct answer is option (3). \bigskip
