Question

Identify the product(s) of the following two reactions (i) and (ii):

• A.
• B.
• C.
• D.

Hint:

The nucleophilic substitution reaction with NaI/acetone favors an SN2 mechanism, leading to the replacement of a halide (Br) by an iodide (I) group.

Answer 1

The Correct Option is B

In reaction (i), the reaction with NaI/acetone leads to a nucleophilic substitution of the bromine atom by the iodide ion, forming the product \( \text{Me} - \text{C} - \text{CH}_2 - \text{I} \). In reaction (ii), a similar substitution occurs, but the iodide replaces the bromine atom, leading to the product \( \text{Me} - \text{C} - \text{CH} - \text{I} \).
Thus, the correct product from both reactions is an iodide substitution on the alkyl chain.
