In most amines, the nitrogen atom is hybridized, with a pyramidal structure and bond
Chapter 0, Problem 2-29(choose chapter or problem)
In most amines, the nitrogen atom is hybridized, with a pyramidal structure and bond angles close to 109. In urea, both nitrogen atoms are found to be planar, with bond angles close to 120. Explain this surprising finding. (Hint: Consider resonance forms and the overlap needed in them.)
