Anitrogen atom can undergo sp2 hybridization when it becomes part of a carbon–nitrogen double bond, as in h2c=nh. (a) using a sketch, show the electron configuration of sp2 hybridized nitrogen just before the overlapping occurs to make this double bond. (b) using sketches (and the analogy to the double bond in c2h4), describe the two bonds of the carbon– nitrogen double bond. (c) describe the geometry of h2c"nh (using a sketch that shows all expected bond angles).
