Answer 1

Note that the given reaction is an electrophilic addition of HCl to the diene system Hence, we can write the mechanism as follows: H -C: CI: Note that we are looking for the form ation of the more stable thermodynamic product, which will be a more substituted alkene. Hence, the nucleophile a wont attack the +ve charge center directly, instead it will rearrange to a primary carbocation to form the more substituted alkene. Note the kinetic product that would have formed is CI Note, this product on the right is substituted at three positions and hence is the thermodynamic product.
