Problem: 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 planar molecular geometry around the nitrogen determine the electron geometry about each interior atom.

FREE Expert Solution

We’re being asked to determine the electron pair and molecular geometry of each interior atom of acetamide (CH3CONH2) and what resonance structure could explain that the nitrogen atom has a planar geometry



The possible electron pair and molecular geometries are:



To do so, we first need to draw a Lewis structure. 


For this, we need to do the following steps:

Step 1: Determine the central atom in this molecule.

Step 2: Calculate the total number of valence electrons present.

Step 3: Draw the Lewis structure for the molecule.

Step 4: Determine the electron pair geometry/molecular geometry of the molecule.
