b)
Interpretation:
The product of the reaction shown if the reaction was conducted in DMSO with water is to be given. The complete mechanism of the reaction including appropriate regiochemistry and stereochemistry is also to be given.
Concept introduction:
The addition of halogens to alkenes in the presence of aqueous DMSO results in the anti addition of the halohydrin, HOX, to the double bond. In the first step a cyclic halonium ion is formed by the attack of the double bond on the halogen. In the second step water attacks the halonium ion from the least shielded side to give an anti addition product. The addition obeys Markovnikov orientation. The negative part (OH) adds to the doubly bonded carbon atom which has more number of substituents.
