(b)
Interpretation:Mechanism for the reaction of hydrogen bromide with alkene indicated should be written.
Concept introduction:Alkenes are considered electron rich and undergo addition reaction in presence of electrophilic halo acids. The product formed is governed by Markovnikov’s Rule. Rule suggests that negative part of halo acid HX must go to the carbon that has more alkyl substituents or less
