Class 11 Chemistry Chapter 4 Chemical Bonding and Molecular Structure – Important Topics

Chemical bonding exists between molecules of the same or different elements. It also exists between the subatomic particles. Some of the different types of bonding are:

Ionic/ Electrovalent Bond: This bond is established by the exchange of oppositely charged ion commonly taking place in a metal and non metal (eg: Sodium and Chlorine).
Covalent Bond: Covalent bonding is where electrons are shared between the participating molecules.
Nuclear Bond: This is the bonding force that keeps the protons and neutrons together inside the nucleon.

Lattice Enthalpy of an ionic solid is defined as the energy required to completely separate one mole of a solid ionic compound into gaseous constituent ions.

Types of bonds can be characterized based on the bond parameters. Some of the bond parameters are:

Bond length
Bond angle
Bond enthalpy
Bond order
Resonance structures

Hybridisation is the process of intermixing the orbitals of slightly different energies to redistribute their energies resulting in the formation of new sets of orbitals of equivalent energies and shapes. The various hybridisation are:

sp
sp²
sp³
sp³d
sp³d²
