We’re being asked to explain why the geometry about N in the molecule is nearly planar and to determine the molecular and electron geometry of each interior atoms.
The possible electron pair and molecular geometries are:
To answer this question, we first need to draw a Lewis structure of the given organic compound.
Draw the Lewis structure for acetamide (CH3CONH2), an organic compound, and determine the geometry about each interior atom. Experiments show that the geometry about the nitrogen atom in acetamide is nearly planar. What resonance structure can account for the planar geometry about the nitrogen atom?
In resonance structure that would have a trigonal pyramidal molecular geometry around the nitrogen determine the electron geometry about each interior atom.
