Hybridization is the mixing of atomic orbitals to form new hybrid orbitals, which are suitable for chemical bonding. The total number of atomic orbitals before mixing always equals the number of newly formed hybrid orbitals. In methane, four atomic orbitals (one 2s and three 2p) mix to form four sp3 hybrid orbitals—we will explain this in detail later on.

Thermodynamic System

In chemistry, our concern is not with the absolute value of enthalpy but rather the change in the enthalpy. The absolute enthalpy cannot be estimated directly since the value of the absolute internal energy cannot be reckoned for real systems. Further, in chemistry and thermodynamics, we are interested in measuring the change in enthalpy, not its absolute value.

Coordination Compounds

Central metal atom of a coordination compound can possess two kinds of valencies i.e. primary valency and secondary valency, and these valencies determine the structure of a coordination compound.

Organic Chemistry

Chemistry is the subject of different elements of the Mendeleev’s periodic table, reactions and mechanisms, physical and chemical properties and finally the application of these elements. There are 118 elements reported in nature and only one element, which is carbon [Atomic no 6, symbol C] is founder of organic chemistry discipline.
