Interpretation:
Mechanism for the given reaction has to be drawn.
Concept Introduction:
Addition reactions are the one in which the groups are added to an unsaturated double bond. The double bond is destroyed because the groups are added across the double bond. If the considered
When two similar groups are added across a double bond, regiochemistry is irrelevant. When adding two different groups across the double bond of an unsymmetrical alkene, the regiochemistry becomes relevant. In simple words, it can be said that, when two different groups are added across a double bond, then regiochemistry becomes relevant.
Markovnikov Addition
In the vinylic bond, if the bulky group gets substituted in the carbon atom that is more substituted means, it is known as Markovnikov’s addition.
anti-Markovnikov Addition
In the vinylic bond, if the bulky group gets substituted in the carbon atom that is less substituted means, it is known as anti-Markovnikov’s addition.
When hydrogen halide is added across a double bond, two key steps are involved and they are proton transfer, nucleophilic attack.
In proton transfer step a carbocation is generated by proton transfer to the alkene. The formed carbocation is attacked by nucleophile to give the product.
