Consider three gaseous alkylamines A, B and C or 1°, 2° and 3° respectively. What will be the correct order of their basicity?
Consider three gaseous alkylamines A, B and C or 1°, 2° and 3° respectively. What will be the correct order of their basicity? Correct Answer C > B > A
In the gaseous state, the solvation effect is missing and hence the expected order of basicity will be 3° > 2° > 1°. This is because as the number of alkyl groups increase, the +I effect strengthens and more negative charge is accumulated on the N atom. This makes the unpaired share mire available for sharing with the proton of the acid.
