Bromination of Higher Alkanes: Selectivity Brominations of alkanes proceed much more slowly than chlorinations, but with much greater selectivity. CH 3 -C-CH 3 CH 3 H Br 2 h ! , 127 o C CH 3 -C-CH 2 Br CH 3 + CH 3 -C-CH 3 CH 3 Br H tert-butyl bromide isobutyl bromide (>99%) (trace) isobutane A lower estimate of site selectivity can be calculated by assuming a product mixture of 99/1. Product Mixture = tert-butyl bromide isobutyl bromide = 99 1 = Statistical Factor x Reactivity 3 o -H Reactivity 1
