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......
Please help with 1 & 2 A. Go through the steps of listing and labeling reactive features and analyzing the reaction between nucleophile and electrophile and resolving each reactive situation leading to the final product formation. Show stereochemistry if appropriate and relative amounts of products. (Z)-pent-2-ene with HBr 3-methylbut-1-ene with HBr and trace amounts of H2O2
