Can be used to synthesize alkyl … 17/11/2015 · This organic chemistry tutorial video discusses the free radical bromination reaction between an alkene and NBS. It provides the reaction mechanism for NBS as well. NBS is known as N 11/01/2016 · Electrophilic addition of Br2 to isoprene yields 3,4-dibromo-3-methyl-1-butene (21%) over 3,4-dibromo-2-methyl-1-butene (3%) product. The mechanism involves the attack of pi-electrons of the isoprenen onto the electrophilic end of Br2 molecule to generate a tertiary carbocation as …

Bromine attacks triolein at three places where double bonds exist in the structure, causing saturated molecule. The equation for the reaction of triolein with bromine is C57 H104 06 + 3 Br2 Electrophilic addition of Br2 to isoprene yields 3,4-dibromo-3-methyl-1-butene (21%) over 3,4-dibromo-2-methyl-1-butene (3%) product. The mechanism involves the attack of pi-electrons of the isoprenen onto the electrophilic end of Br2 molecule to generate a tertiary carbocation as the major intermediate
