Petroleum Refining is defined as the industrial process of production of useful petroleum products from crude oil. The crude oil in its raw form is a dark and sticky liquid which is not useful. To get the usable products from the crude oil, it needs to be refined.
Chirality is an important property of asymmetry in many branches of science. A chiral molecule or ion exists in two stereoisomers that are mirror images of each other, called enantiomers
Elastomers are polymers showing properties of both viscosity and elasticity and are also called viscoelasticity. The molecules of elastomers held together by weak intermolecular forces
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
