If the measurement of basic strength is conducted strictly in the gaseous phase, eliminating the com — GOC and Organic Chemistry Basics Chemistry Question

💡 Solution & Explanation

In the gas phase, the stabilization of the conjugate acid depends purely and exclusively on the inherent electronic effects of the molecule. Alkyl groups exert an electron-donating $+I$ inductive effect. The tertiary amine has three alkyl groups maximizing electron density on the nitrogen, making it the strongest base. The order follows strictly as $3^\circ > 2^\circ > 1^\circ > NH_3$.
