Vedclass · Answer

(D) The basicity of the molecules depends on the availability of the lone pair on the nitrogen atom.In molecule $(R)$,the lone pair on the nitrogen atom is localized because the bridgehead nitrogen cannot participate in resonance with the carbonyl group due to Bredt's rule,which prevents the formation of a double bond at the bridgehead position.In molecule $(Q)$,the lone pair on the nitrogen atom is involved in resonance with the carbonyl group. Additionally,there is cross-conjugation with the double bond,which further reduces the availability of the lone pair.In molecule $(P)$,the lone pair on the nitrogen atom is involved in resonance with the carbonyl group,making it less basic than $(R)$ but more basic than $(Q)$ because $(Q)$ has additional cross-conjugation.Therefore,the correct order of basicity is $R > Q > P$.

The correct order of basicity for the following molecules is $:$
