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......

E. Just as with isolated alkenes, electrophilic addition of H-X occurs with conjugated dienes. The electron pushing mechanisms are the same. Often, two products are formed: 1,2-addition and 1,4-addition products. For the reaction below, provide a detailed mechanism which explains the formation of the two products. Label each product as 1,2-addition and 1,4-addition. Show all electron movement with arrows and all intermediates. Which product will predominate at -80 °C and at 40 °C. HBr F.

Electrophilic addition of bromine, Br2, to alkenes yields a 1,2-dibromoalkane
Electrophilic addition of bromine, Br2, to alkenes yields a 1,2-dibromoalkane. The reaction proceeds through a cyclic intermediate known as a bromonium ion. The reaction occurs in an anhydrous solvent such as CH2Cl2In the second step of the reaction, bromide is the nucleophile and attacks at one of the carbons of the bromonium ion to yield the product. Due to steric clashes, the bromide ion always attacks the carbon from the opposite face of the bromonium ioa so that a product...

Draw the structure of the product of each step in the following three-step synthesis. If a nitro group is in the structure, use the functional group tool to put it in, do not draw it out (i.e. put in NO2). Although the first step produces a mixture of isomers, the para isomer is isolated as the sole product of interest and used in the second step. Give only the major product for the second and third steps. HNO Brz Br2...

REVIEW Topics [References) CH HC OCH Br2 CH3 B H3C CH,OH H₂C CH₂ Electrophilic addition of hypohalous acids to alkenes yields a 1,2-haloalcohol called a halohydrin. Halohydrin formation, however, does not result from the addition of HOBr, for example. Instead the addition is done indirectly by reaction of the alkene with Br, in the presence of water. The reaction also works with Cl2 to give chlorohydrins instead of bromohydrins. The reaction proceeds through a cyclic intermediate known as...
