In an aqueous solution, what is the correct decreasing order of basic strength specifically for ethy — Amines Chemistry Question

💡 Solution & Explanation

For the larger ethyl group, the +I effect is much stronger, pushing the 3° amine ahead of the 1° amine despite poor hydration. However, the 2° amine maintains the optimal thermodynamic balance, resulting in the order $2^\circ > 3^\circ > 1^\circ > NH_3$.
