Question

In most of the amines, the nitrogen has an sp³ hybridization with a pyramidal geometry having bond angles close to 109°. In contrast, the nitrogen atom in methanamide has sp² hybridization and trigonal planar geometry with bond angles of 120°, approximately. Explain this unusual behavior.

Chemical structure of methanamide, illustrating sp2 hybridization and trigonal planar geometry.
