WebMain Reaction and Mechanism : The first step of a free-radical chain reaction is initiation, where a reactive intermediate radical is produced. Initiation often needs heat or light to get the reaction ... The chlorine radical produced during initiation reacts with 1-chlorobutane to produce a 1-chlorobutane radical. This new radical reacts WebMar 5, 2015 · The answer in the back of the book says it will be 2-chloro-3-methylbutane. However, I thought the major product would be 2-chloro-2-methylbutane. The later is formed through a tertiary free radical with eight hyper-conjugative structures, whereas the former forms through a secondary free radical with only four hyper-conjugative structures.
