Vedclass · Answer

(A) The basicity of amines depends on the availability of the lone pair on the nitrogen atom. $(I)$ Piperidine: The nitrogen is $sp^3$ hybridized,and the lone pair is localized. It is a strong base. $(II)$ Pyridine: The nitrogen is $sp^2$ hybridized. The lone pair is in an $sp^2$ orbital,which is more electronegative than an $sp^3$ orbital,making it less basic than piperidine. $(III)$ Morpholine: Similar to piperidine,but the oxygen atom exerts an electron-withdrawing inductive effect ($-I$ effect),which decreases the electron density on the nitrogen,making it less basic than piperidine. $(IV)$ Pyrrole: The lone pair on the nitrogen is involved in the aromatic sextet ($6\pi$ electrons),making it unavailable for protonation. Thus,it is the least basic. Comparing these,the order of basicity is: Piperidine $(I) >$ Morpholine $(III) >$ Pyridine $(II) >$ Pyrrole $(IV)$.
