For this problem, we have to draw the kinetic and thermodynamic products of the reaction below
Recall that alkenes are converted to alkyl halides via hydrohalogenation, which occurs in two steps:
(1) protonation – the alkene is protonated, forming a carbocation intermediate and a halide ion. This follows Markovnikov’s rule, which states that the more stable carbocation is formed.
Also, since a carbocation is formed during the reaction, the carbocation may rearrange into a more stable one.
(2) nucleophilic attack – the halide ion comes in and attacks the positively-charged carbon. The stereochemistry for this reaction is unknown since the nucleophile can attack either side of the empty p-orbital.
However, we have 2 consecutive double bonds which make this a conjugated hydrohalogenation.
What are the expected kinetic and thermodynamic products from the addition of one mole of Br2 to the following dienes?
