Answer on Question#52196 - Chemistry
... due to the unrealized presence of free radical generating substances such as peroxides. The explanation is that HBr produces a Br radical, which then reacts with the double bond. Since the bromine atom is very large, it is more probable that it will encounter and react with the least substituted car ...
