Question
Propose a structure for a conjugated diene that gives the same product from both 1,2 and 1,4 addition of HBr.
Step 1
In 1,2 addition, the hydrogen atom from HBr adds to one end of the diene and the bromine atom adds to the adjacent carbon atom. In 1,4 addition, the hydrogen atom adds to one end of the diene and the bromine atom adds to the carbon atom three positions away. Show more…

Conjugated dienes react with radicals by both 1,2- and 1,4-addition. Write a detailed mechanism to account for this fact using the pcroxide-promoted addition of one molar equivalent of HBr to 1,3 -butadicne as an illustration.
Give the structures of both 1,2 and 1,4 adducts resulting from reaction of 1 equivalent of $\mathrm{HCl}$ with 1,3 -pentadiene.
