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.
Pre-Requisites:
Organic chemistry
Activity:
Aromatic compounds.
Real Life Question:
What is organic chemistry?
Key Words / FlashCards
| Key Words | Definitions (pref. in our own words) |
|---|---|
| Organic compound | An organic compound is any member of a large class of gaseous, liquid, or solid chemical compounds whose molecules contain carbon. |
Learning aids / Gadgets
| 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.

Practical examples around us
| 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:
The structural formula of a chemical compound is a graphic representation of the molecular structure, showing how the atoms are arranged.
What you learn in Practice:
A bond line-angle formula is in which carbon atoms are implied at the corners and ends of lines, and each carbon atom is understood to be attached to enough hydrogen atoms to give each carbon atom four bonds.
