Assuming reactions are strictly in the gaseous phase (ignoring solvation), which of the following or — GOC and Organic Chemistry Basics Chemistry Question

💡 Solution & Explanation

In the gas phase, basicity correlates with the $+I$ effect. Ethyl has a stronger $+I$ effect than methyl (Option A). Dimethylamine has two $+I$ groups vs one in methylamine (Option B). In $NF_3$, highly electronegative fluorine exerts a strong $-I$ effect, deeply pulling electron density away from nitrogen, making $NH_3$ much more basic (Option C).
