A nitrogen atom can undergo sp2 hybridization when it becomespart of a carbon–nitrogen double bond, as in H2C=NH.

(a) Using a sketch, show the electron configuration of sp2hybridized nitrogen just before the overlapping occurs to make thisdouble bond.

(b) Using sketches (and the analogy to the double bond in C2H4),describe the two bonds of the carbon– nitrogen doublebond.
