Which of the following best describes the role of water in the deprotonation of the G-acid?A)     AcidB)     CatalystC)     BaseD)     Aprotic solvent

To determine the role of water in the deprotonation of G-acid, let's analyze the options provided in detail:

1. Acid: Water can act as an acid in some reactions, but in the context of deprotonation, it is more relevant to consider it in other roles.

2. Catalyst: A catalyst facilitates a reaction without being consumed, but the deprotonation process typically involves direct participation in a reaction mechanism that goes beyond mere facilitation.

3. Base: Water can act as a base by accepting a proton (H⁺) from an acid, thus, playing a critical role in the deprotonation process.

4. Aprotic solvent: An aprotic solvent does not donate protons, which is not the case for water as it can donate protons in an acid-base reaction.

Based on this analysis, the best description of the role of water in the deprotonation of G-acid is:

Final Answer

C) Base
