3 - Methylhex-2-ene on reaction with HBr in presence of peroxide forms an addition product (A). The number of possible stereoisomers for ' A ' is ________.

Correct answer

0

Step-by-step solution

The hydrogen bromide addition in peroxides follows Anti Markovnikov rule. Anti Markovnikov addition reaction is found to follow a free radical mechanism. The peroxide compound involved helps in the generation of free radicals. The Anti-Markovnikov rule defines regiochemistry in which the substituent is attached to a less substituted carbon instead of the more substituted carbon. The reaction of 3 - Methylhex-2-ene with HBr in presence of peroxide, takes place as follows, 2 chiral carbons, here, so, total number of
