Bromination of anisole with br2 in cs2 gives
WebBromination of methoxybenzene (anisole) is very fast and gives mainly the para-bromo isomer, accompanied by 10% of the ortho-isomer and only a trace of the meta-isomer. Bromination of nitrobenzene requires strong heating and produces the meta-bromo isomer as the chief product. WebRank the compounds in each group in order of decreasing reactivity in electrophilic aromatic substitution. aniline -> toluene -> benzylamine. Classify each substituent as ortho, para activators; ortho, para deactivators; or meta deactivators. o,p activators: anisole (OCH3), phenol, aniline, tert-butylbenzene.
