What is the primary purpose of using strong bases in organic reactions?

• A. To promote the formation of esters
• B. To catalyze hydrolysis reactions
• C. To deprotonate acids and increase nucleophilicity
• D. To precipitate metal ions

Answer: (C)

The primary purpose of using strong bases in organic reactions is to deprotonate acids and increase nucleophilicity. In organic chemistry, strong bases are highly effective at removing protons from acidic functional groups. This deprotonation enhances the nucleophilicity of the remaining species, allowing them to participate more readily in nucleophilic substitution or addition reactions. For instance, when a strong base deprotonates an alcohol, the resulting alkoxide ion becomes a much more powerful nucleophile compared to the neutral alcohol. This increased nucleophilicity can facilitate subsequent reactions, such as alkylation or reactions with electrophiles, where the nucleophile can effectively attack. In contrast, while ester formation does involve reactions with bases, it typically requires a neutral nucleophile and is not primarily driven by the presence of a strong base. Hydrolysis reactions may benefit from basic conditions, but they do not specifically require a strong base to proceed. Lastly, using strong bases to precipitate metal ions is a more specialized application and not a primary use in most organic reactions. Thus, the role of strong bases as deprotonators that significantly enhance nucleophilicity is a foundational concept in organic chemistry.
