Covalent and Ionic Bonds

Atoms of different elements except noble gases do not have a complete octet, so they combine with other atoms to form a chemical bond. When two atoms of the same and different elements mutually share two electrons, one by one, to form a bond between them…

Carbon Bonding

It is basically an association between two C that is formed by sharing a pair of electrons among them. Commonly, this is a single or sigma (σ) bond. Sometimes double or triple or pi (Π) bonds can also be formed. These are formed when orbitals of two C at…

Alcohols, Phenols and Ethers

Alcohols are hydroxyl (-OH) group or moiety containing organic aliphatic molecule. They are produced when a hydrogen atom of an aliphatic compound is substituted with hydroxyl moiety. The general expression of alcohol is R-OH, where the R is an aliphatic…
