The reaction of what nucleophile and substrate is represented by the following transition state?

Question

Quizplus · Accepted Answer

The transition state shown in the image represents a nucleophilic substitution reaction where the nucleophile attacks the substrate, leading to the formation of the product. The presence of a negative charge on the nucleophile indicates that it is an anionic species. Methoxide, CH3O-, is a strong nucleophile and is often used in SN2 reactions. Also, the substrate has a leaving group (bromine) attached to a secondary carbon, which makes it a good substrate for SN2 reactions. Therefore, the best choice that matches the given transition state is methoxide with 2-bromopropane. Hence, option B is correct.
