In the gaseous phase, what is the correct order of basicity for primary, secondary, and tertiary ami

Q: What is the correct answer for CBSE12?

The correct answer is C. In the gaseous phase, the basicity of amines is primarily determined by the +I effect of alkyl groups, which increases electron density on the nitrogen atom, making the lone pair more available for protonation. More alkyl groups lead to a stronger base. Thus, the order is Tertiary amine > Secondary amine > Primary amine > NH3.
