Biological Oxygen Demand (BOD) estimates the amount of biodegradable organic matter that is present in polluted waters, effluents and polluted waters

It is a theoretical model which details the molecular composition of the gas in terms of a huge number of sub microscopic particles that contain both atoms and molecules.

Diastereomers are compounds that can be defined as having similar sequence of bonded elements and same molecular formula, they are however non superimposable and non-mirror images

the particles that have a dimension with respect to their external, internal and surface structure and lie in the range of 1nm to 100nm are called as Nanoparticles

At equilibrium Nernst equation is given by,
E0 = (2.303RT/nF) log10Keq
Where, Keq = equilibrium constant and F= faradays constant, and gives a relation between standard electrode potential.

Quantum number is a value that is used to indicate the energy that is present in atoms and molecules, in addition an electron that exists within an ion or atom has four such numbers to exhibit the energy state

Amines are functional groups and compounds having a basic nitrogen atom with a lone pair. In other terms amines are the derivatives of ammonia(NH3)

Saponification is the hydrolysis of an ester with NaOH or KOH to give alcohol and sodium or potassium salt of the acid.

The Molecular orbital theory was utilised initially to emphasize the bonding in molecules as the valence band theory could not explain the bonding in molecules.
