Which of the following is NOT shown by a Lewis dot structure?

a). the three-dimensional geometry of the bonded atoms

b). the number and symbols of atoms present

c). the way atoms connect to each other within the molecule

d). the total number of valence electrons from all atom in the molecule

Answer: -

a). the three-dimensional geometry of the bonded atoms.

Explanation: -

In a Lewis dot structure, the bonding between the atoms present in a molecules well as the number of non bonded electrons present in each molecule are shown via chemical symbols as a diagram.

Thus the lewis dot diagram shows how the atoms are connected to each other within the molecule.

The total number of valence electrons from all the atom in the molecule are also shown.

But a Lewis dot structure cannot give any information about the three-dimensional geometry of the bonded atoms.
