Reaction of Dimethyl Sulphoxide with Acetophenone in the Presence of HBr(aq)

Introduction:
The given reaction is an organic chemical reaction that involves the use of dimethyl sulphoxide, acetophenone, and hydrobromic acid. The reaction is carried out in the presence of HBr(aq) and is expected to yield a specific product.

Reaction:
Dimethyl sulphoxide reacts with acetophenone in the presence of HBr(aq). The expected products are:

1. C6H5CoCH2OH (Phenyl-2-propanol)
2. C6H5COCHO (Acetophenone Oxime)
3. C6H5COCOOH (Phenylacetic acid)
4. No Reaction

Results:
The reaction yields Phenyl-2-propanol (C6H5CoCH2OH) as the main product. The reaction involves the formation of an intermediate carbocation, which reacts with HBr(aq) to yield the product.

Explanation:
The reaction is a nucleophilic addition reaction, where the nucleophile attacks the carbonyl carbon of the acetophenone, forming an intermediate carbocation. The carbocation is then attacked by the HBr(aq), yielding the product Phenyl-2-propanol.

Conclusion:
In conclusion, the reaction of dimethyl sulphoxide with acetophenone in the presence of HBr(aq) yields Phenyl-2-propanol as the main product. The reaction involves the formation of an intermediate carbocation, which reacts with HBr(aq) to yield the product.
