1.	In the common naming system, the prefix sym- is used for haloarenes with _____ halogen atoms.(a) 1(b) 2(c) 3(d) 4I got this question in exam.The doubt is from Haloalkanes Nomenclature in division Haloalkanes and Haloarenes of Chemistry – Class 12
Answer» The correct choice is (c) 3 Explanation: The prefix sym- is used for trihaloarenes with same HALOGEN atom at ALTERNATE POSITIONS in the benzene ring (1, 3, 5). The prefixes o-, m- and p- are used for dihaloarenes depending on the RELATIVE positions of the two identical halogen atoms on the aromatic ring.
