Answer :
Answer:
The correct option is D.
Explanation:
VSEPR theory is defined as the shape of the molecules determined by the repulsion between electron pairs in the valence cell. Valence cell electrons are two types:
1) Bonding electrons (sigma bonds)
2) Anti-bonding electrons or lone pairs.
These lone pairs, and bonds helps to form the shape which keeps these electrons separate as possible. For example: two electron pairs forming a linear structure such as CO2 contains two double bonds with zero lone pair electrons, and forming 180 degree bond angles at the carbon (central) atom.
The statement that is always true according to VSEPR theory is:
- The shape of a molecule is determined by repulsions among all electron groups on the central atom (or interior atoms, if there is more than one).
What is VSEPR theory?
It is a theory used as a tool to predict the geometry of molecules, that is, the way the molecule is ordered in space.
Characteristics of VSEPR theory
- It focuses mainly on the maximum distance that the lone pairs must maintain in the organization of the electron cloud around the central atom.
- It assumes that the electrons are placed as far away from each other as possible, so that the repulsion between the pairs is the minimum.
Therefore, we can conclude that the main goal of VSEPR theory is the determination of molecular shapes.
