29. halide and ãy other organic and inorganic reagets (7 points) Br 3-bromo-4-methylphenon BONUS: For 8 extra points, answer the following questions: Before the advent of spectroscopy, Körmer's absolute method was used to determine whether a disubstituted benzene was ortho, meta or para. Körner's method involves adding a third group (often a nitro) and determining hovw many isomers are formed. For ex are formed, although in different percentages. NO2 isomers could theoretically be formed by nitration b) How many isomers could theoretically be formed by nitration could of m-xylene? Show them. a) How many of p-xylene? Show them. c) Around 1900 a chemist isolated an aromatic compound of molecular formula C.H.Bro. He carefully nitrated this compound and purified 3 isomers of formula CH BrNO. Propose structures for the original compound and the 3 nitrated derivatives
