Chapter 9, Problem 103RQ

A nitrogen atom can undergo $s{p}^2$ hybridization when it becomes part of a carbon-nitrogen double bond, as in

${\text{H}}_{\text{2}}\text{C=NH}$.

(a) Using a sketch, show the electron configuration of $s{p}^2$

hybridized nitrogen just before the overlapping occurs to make this double bond.

(b) Using sketches (and the analogy to the double bond in ${\text{C}}_{\text{2}}{\text{H}}_{\text{4}}$), describe the two bonds of the carbon- nitrogen double bond.

(c) Describe the geometry of ${\text{H}}_{\text{2}}\text{C=NH}$

(use a sketch to show all the expected bond angles.)
