In the strictly gaseous phase (devoid of hydration effects), the correct decreasing order of basic s — GOC and Organic Chemistry Basics Chemistry Question

💡 Solution & Explanation

In the gaseous phase, there is no water to provide solvation (hydration) stabilization. Basic strength relies entirely on the $+I$ effect of the alkyl groups pumping electron density onto the nitrogen. Thus, the tertiary amine (three $+I$ groups) is the strongest base.
