Why it is difficult to accurately represent ammonia two-dimensionally?

Question

Mrs. Rebekah Dickinson MD · Accepted Answer

According to the valence shell electron pair repulsion (VSPER) theory, an ammonia molecule  has a trigonal pyramidal shape with an experimental bond angle measure of 106.7 degrees. This is why it is difficult to accurately represent ammonia two-dimensionally because the molecular structure entails a 3-D projection with angles in it unlike the linear structure.

Mrs. Rebekah Dickinson MD · Answer

The correct answer is because the molecular structure.Explanation:The difficulty of ammonia and methane to be represented on paper is due to the molecular structure. These compounds have a three-dimensional projection with defined angles. Ammonia presents angles of 109.5º between the atom of Nitrogen and those of Oxygen. The ammonia presents 107.8º between the oxygen atoms.In the methane molecule, there is 109.5º between the hydrogen molecules and the carbon atom. This results in the need for a 3D representation of the molecule. Have a nice day!
