Answer 1

dng OBY urlbenzene Valid namis; i) 1-bromo-3-methylben ü) 3-buomotoluene vii) m-bromotoluene iv) meta -buonomethylbenzene So all oftions que correct, Sus 2 a) Cyclohexane and Benzene both show peak Ux3100 and 1600 so can't be distinguished Both show =(-1 stretch at 800 can and C=C stretch at ~1600an. b) Benzene shows only one peak at n7ppm in NMR where cyclohexene shows 3 at 5, 2 and lappm. So can be distinguished using the given values C) 13C NMR of both show peak at ~30ppm por double bonded carbon. They can be distinguished by number of peaks but not by peak at ~130 ppm. So only option is is Cams Vander correct,
