Organic Chemistry

Octahedral Geometry

When an atom is surrounded by six substituents, arranged in a manner that four are in one plane, one above and below, and their vertices join to give eight faces (octa-hedrons), such a molecular geometry is octahedral.

Since it looks like two pyramids projecting out from a square base, the geometry is also called square bipyramidal.

 

What is the priority order in polyfunctional compounds while assigning nomenclature?

IUPAC, an international body engaged in developing standards for naming chemical elements and compounds, has laid several rules known as 'IUPAC rules' to identify a molecule by its parent alkane chain and the functional group. It has assigned various suffixes to identify organic chemistry's commonly seen functional groups.

London Dispersion Force

London Dispersion, a type of Vander Waal Force, is the weakest of the three types, yet, it is the only one universally present in all the atoms and molecules.

In most cases, it is present in addition to the other forces; however, it is exclusively observed in nonpolar atoms and molecules devoid of any functional groups and, therefore, possess no other overpowering interactions. Examples are He, CH4, I2, C(CH3)4, etc.
