Sub Topic Name : Types Of Molecular Orbitals |
• Molecular orbitals of diatomic molecules are of 3 types: 1. Sigma, 2. Pi and 3. Delta Sigma bonding and antibonding molecular orbitals are symmetric along the bonding molecular plane while pi molecular orbitals are not.
Covalent bond, polyatomic molecule , atomic and molecular orbital
Many things in nature are symmetrical e.g. insects, leaves.
Why are things having symmetry?
Key Words | Definitions (pref. in our own words) |
---|---|
Molecular orbital | Orbitals formed when atomic orbitals combine by hybridisation. |
Gadgets | How it can be used |
---|---|
Square piece of paper, circular piece of paper, | Fold the papers and see whether they are symmetrical or not. |
Symmetry helps to group things.
Zoo, garden.
Examples | Explainations |
---|---|
Leaves, insects | Notice the symmetry in the structure of things for ex: leaves and insects about a single plain or more than one plain. |
Molecular orbitals are of three types: sigma, pi and delta.
Similar energies are important for atomic orbitals to combine.
