Lewis acids and bases are most closely associated with which process? a)  proton transferb)  electron transferc)  the formation of aqueous ionsd)  the formation of a conjugate acid or base

B) Electron transfer

Explanation:

According to Arrhenius concept, a base is defined as a substance which donates hydroxide ions when dissolved in water and an acid is defined as a substance which donates hydronium ions in water.

According to the Bronsted Lowry conjugate acid-base theory, an acid is defined as a substance which donates protons and a base is defined as a substance which accepts protons.

According to the Lewis concept, an acid is defined as a substance that accepts electron pairs and base is defined as a substance which donates electron pairs.

Thus Lewis acids and bases are most closely associated with the process of Electron transfer.

if you mean hydrogen and oxygen then water is the product
