Introduction

Organic chemistry is a chemistry sub discipline involving the scientific study of the structure, properties, and reactions of organic compounds and organic materials, i.e., matter in its various forms that contain carbon atoms.

Gadgets How it can be used
Alcohols Alcohols (R-OH) take the suffix "-ol" with an infix numerical bonding position: CH3CH2CH2OH is propan-1-ol. The suffixes -diol, -triol, -tetraol, etc., are used for multiple -OH groups: Ethylene glycol CH2OHCH2OH is ethane-1, 2-diol.
Real life uses :

Study the nature of chemicals.

Examples Explainations
ketones In general ketones (R-CO-R) take the suffix "-one" with an infix position number: CH3CH2CH2COCH3 is pentan-2-one. If a higher precedence suffix is in use, the prefix "oxo-" is used: CH3CH2CH2COCH2CHO is 3-oxohexanal.
What you learn in Theory:

At standard temperature and pressure, oxygen is a colorless, odorless gas with the molecular formula O2, in which the two oxygen atoms are chemically bonded to each other with a spin triplet electron configuration. This bond has a bond order of two, and is often simplified in description as a double bond or as a combination of one two-electron bond and two three-electron bonds.

What you learn in Practice:

The solubility of oxygen in water is temperature-dependent, and about twice as much (14.6 mg•L?1) dissolves at 0 °C than at 20 °C (7.6 mg•L?1).
