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.

Key Words / FlashCards
Key Words Definitions (pref. in our own words)
Gas chromatography Gas chromatography (GC), is a common type of chromatography used in analytical chemistry for separating and analyzing compounds that can be vaporized without decomposition.
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.

Places to visit :

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 ionic compounds formed during the fusion are extracted in aqueous solution and can be detected by simple chemical tests. The extract is called sodium fusion extract or Lassaigne's extract.

What you learn in Practice:

Ferric ions generated during the process react with ferrocyanide to form prussian blue precipitate of ferric ferrocyanide.
