उत्तर
- IUPAC name of the product: 1-Bromo-2-methylpropane
- Anti-Markownikov’s rule/Kharasch effect/peroxide effect: It states that the addition of HBr to an unsymmetrical alkene in the presence of organic peroxide (R–O–O–R) takes place in the opposite orientation to that suggested by Markovnikov's rule.
