Name and structure of functional groups

Functional Groups in Organic Chemistry

In the field of organic chemistry, functional groups are specific groups of atoms that are like the “personality traits” of molecules. Just as the behavior of a person is influenced by their characteristics, the chemical behavior of organic molecules is…

Hund's rule of maximum multiplicity.

Hund’s Rule of Maximum Multiplicity

Hund’s Rule of Maximum Multiplicity, commonly known as Hund’s Rule, deals with the filling of electrons into orbitals belonging to the same subshell or orbitals of equal energy, known as degenerate orbitals. This rule was proposed by a German physicist,…

Pauli Exclusion Principle

Pauli Exclusion Principle: Definition, Examples

In this chapter, we will learn about Pauli Exclusion Principle. You have studied in the quantum mechanical model of atom, the state of each electron in an atom is described by four quantum numbers: An Austrian theoretical physicist Wolfgang Ernst…

Aufbau principle

Aufbau Principle

In this chapter, we will learn about the Aufbau principle. Filling of electrons into the orbitals of different atom take place according to Aufbau principle, which is based on the Pauli’s exclusion principle, Hund’s rule, and the relative energies of…

Shapes of 1s and 2s orbitals.

Shapes of Orbitals

In this chapter, we will learn about shapes of orbitals. We know that an atomic orbital is the three-dimensional region or area in space around the nucleus in which the tendency of finding an electron is maximum. The square of…
