Chemistry - GOC Question with Solution | TestHub

The resonance structures for RCOG are

or
Electron-release from G(H,$\mathrm{C}{\mathrm{H}}_3,\mathrm{O}\mathrm{C}{\mathrm{H}}_3$or$\mathrm{N}{\mathrm{H}}_2$) to O stabilizesby diminishing the electrophilic character of carbonyl carbon. Since degree of delocalization is maximum in case of$-\mathrm{N}{\mathrm{H}}_2$, therefore, the properties ofis suppressed most in amides$\left(\mathrm{R}\mathrm{C}\mathrm{O}\mathrm{N}{\mathrm{H}}_2\right)$.
