Chapter 1, Problem 82P

The N atom in ${\text{CH}}_{\text{3}}{\text{CONH}}_{\text{2}}$ (acetamide) is $s{p}^2$ hybridized, even though it is surrounded by four groups. Using this information, draw a diagram that shows orbitals used by the atoms in the $-{\text{CONH}}_{\text{2}}$ portion of acetamide, and offer an explanation as to the observed hybridization.
