please help me by answeing part 2. please include mechanism.
Electrophilic addition of HBr to 3-methylbut-1-ene gives a mixture of two constitutional isomers. Only one of the isomers, however, is formed when the 2 methylbut 2 ene reacts with HBr in the presence of peroxides. Draw each of the isomers. Part 1: Draw the isomer that is formed in both reactions Br view structure Part 2 out of 2 Draw the isomer formed only in electrophilic addition reaction. edit structure......

Multistep reaction mechanisms Group ActivityTreating (S)-2-butanol with HBr results in the following two step reaction: Step 1: CH3CH(OH)CH2CH3 + HBr ⇌ CH3CH(OH2)CH2CH3+ + Br-Step 2: CH3CH(OH2)CH2CH3+ + Br- ⇌ CH3CH(Br)CH2CH3 + H2ODraw a mechanism for each step. Draw structures for all reactants and products, including correct stereochemistry (wedges and dashes). Show all the curved arrows in each step, and label each curved arrow according to whether it represents proton transfer, loss of a leaving group, nucleophilic attack, or carbocation rearrangement.
