Question

In the amide group, the carbon is sp^2 hybridized due to the presence of a double bond (C=O) and two single bonds (C-N and C-H or another group), while the nitrogen is sp^3 hybridized as it forms three sigma bonds (one with carbon and typically two with hydrogen or other groups) and has one lone pair.
