Respuesta :
You would continue to receive the same thing. If you had drawn the molecule flipped over in space, the chlorine would be on a carbon atom next to the chain's end. We must examine them independently because if the alkene was asymmetrical, the situation would be different. For this reaction, heat plus HCl will be the proper set.
What does adding hydrogen halides to alkenes (hydrogen and halide) entail?
All alkenes interact with the hydrogen halides in addition reactions. One of the carbon atoms initially in the double bond is joined by a hydrogen atom, and the other by a halogen atom.
For instance, you can create chloroethane using ethene and hydrogen chloride, and 2-chlorobutane using but-2-ene.
General Mechanism:
Because it uses the most basic electrophile, the proton, the addition of hydrogen halides is one of the simplest electrophilic addition reactions. The electrophile proton and the nucleophile are both present in hydrogen halides (halide). The double bond will first be attacked by the electrophile, which will then take up a set of electrons and connect it to the molecule. In essence, this is the opposite of the previous E₁ reaction step (deprotonation step). One carbon-carbon bond with a positive charge will be present in the resultant molecule (carbocation). Following the formation of a bond between the nucleophile (halide) and the carbocation, a new molecule with the initial hydrogen and halide connected to the organic reactant is created. Only when a strong nucleophile is employed can the second step take place.
The HBr, HCl, HI, and HF halides can all take part in this reaction and add on in the same way. Despite the fact that various halides react at varying rates due to the weakening of the H-X bond when X increases (poor overlap of orbitals). The order of reaction rates is HF, HCl, HBr, and HI.
