Concept explainers
Interpretation:
Shape of the molecule
Concept Introduction:
Lewis structures are diagrams that represent the
The chemical bonding present in covalently bonded molecules and in coordination compounds are represented using Lewis structures.
It is also known as Lewis dot structures which represents the bonding between atoms of a molecule and the lone pairs of electrons that may exist in the molecule.
The Lewis structure is based on the concept of the octet rule so that the electrons shared in each atom should have 8 electrons in its outer shell.
Sometimes the chemical bonding of a molecule cannot be represented using a single Lewis structure. In these cases, the chemical bonding are described by delocalization of electrons and is known as resonance.
All the possible resonance structures are imaginary whereas the resonance hybrid is real.
These structures will differ only in the arrangement of the electrons not in the relative position of the atomic nuclei.
Molecular geometry is the shape of a molecule predicted by considering only bond pair of electrons.
The shape of a molecule is described by its arrangement of atoms.
Geometry of different type of molecules with respect to the number of electron pairs are mentioned below,
