a. b.

The 3D image below is that of an allylic carbocation intermediate formed by the protonation of a conjugated diene with $$\mathrm{HBr}$$. Draw a structural formula for the diene. - You do not have to consider stereochemistry. - You do not have to explicitly draw $$\mathrm{H}$$ atoms. - In cases where there is more than one answer, just draw one. The 3D image below is that of an allylic carbocation intermediate formed by the protonation of a conjugated diene with $$\mathrm{HBr}$$. Draw structural formulas for the final reaction products. - You do not have to consider stereochemistry. - You do not have to explicitly draw $$\mathrm{H}$$ atoms. - Separate multiple products using the $$+$$ sign from the drop-down menu.
