Question
### Question Which of the following is the **STRONGEST nucleophile**? #### Options: - **a. I** Structure: A molecule with a triple bond between carbon atoms, and a hydrogen attached to the last carbon. - **b. II** Structure: Similar to option I, but with a negative charge on the last carbon atom instead of a hydrogen. - **c. III** Structure: A molecule with a hydroxyl group (-OH) bonded to a carbon. - **d. IV** Structure: A molecule with an oxygen atom having a negative charge (alkoxide ion). ### Explanation of Structures: 1. **Option I** represents a neutral alkyne. 2. **Option II** shows an alkyne with a negative charge, indicating a carbanion. 3. **Option III** corresponds to an alcohol. 4. **Option IV** depicts an alkoxide ion. ### Diagram Details Each diagram shows a different molecular structure that includes various functional groups and charges. The focus is on identifying the strongest nucleophile, which typically involves assessing the availability of electrons and the stability of each species.
