Which of these species,acting in a protic solvent,exhibits greater nucleophilic activity than expected on the basis of its basicity?

Question

Quizplus · Accepted Answer

In a protic solvent, nucleophilicity does not always correlate directly with basicity due to solvent interactions. Thiolate ions (C) exhibit greater nucleophilic activity than expected based on their basicity because their larger size compared to hydroxide ions (A) and alkoxide ions (B) reduces the extent of solvation, making them more nucleophilic. Chloride ions (D) and water (E) follow more predictable patterns where their nucleophilicity more closely matches their basicity.
