Chemical Bonding and Molecular Structure is an important topic from NEET Chemistry. This topic needs immense preparation and hard work. Here in this article, we are sharing short notes and a few high-quality video classes for the betterment of your NEET preparation.

Chemical Bonding and Molecular Structure

The chemical bond is the attractive force that holds various constituents together in different chemical species

Octet Rule: Chemical bonding allows atoms of various elements to achieve electrical configurations similar to noble gas atoms or to complete their octet. In other words, atoms of all major group elements tend to connect in such a way that each atom has 8 electrons in its valence shell, allowing the atoms to achieve an electrical configuration similar to that of noble gases. As a result of chemical bonding, atoms gain the stability of noble gases.

Lewis Symbols: Only the valence electrons participate in chemical bonding during the formation of a molecule. G. N. Lewis, an American chemist, introduced the use of simple notations to describe valence electrons in an atom. These notations are referred to as Lewis symbols.

Electrovalent Bond: Electrovalent bonds are generated as a result of electrostatic interaction between positive and negative ions. It is also known as an ionic bond.

Factors Influencing Ionic Bond Formation

  1. Ionization Enthalpy
  2. Electron Gain Ethalpy
  3. Lattice Energy
Ionization Enthalpy

The amount of energy required to remove one electron from the outermost shell of an isolated atom in the gaseous phase and turn it into a gaseous positive ion is known as the ionization enthalpy of that element. It is sometimes known as ionization energy.

Electron Gain Enthalpy

The enthalpy change that occurs when an additional electron is added to an isolated atom in the gaseous phase to produce a gaseous negative ion is referred to as an element’s electron affinity or electron gain enthalpy.

Lattice Energy

Lattice enthalpy is the energy generated when the required number of gaseous positive and negative ions combine to create one mole of the ionic molecule.
