  • Aromatic Hydrocarbon
  • Isomers - Stereoisomers
  • Functional Groups



Aromatic Hydrocarbon
Aromatic hydrocarbons, also called aromatic compounds, are compounds that contain benzene as a part of their structure. Benzene is a cyclic hydrocarbon with the formula C6H6

The structure of aromatic hydrocarbons.

This video describes in simple terms the property of resonance as well as the family of organic compounds based on benzene.



Isomers - Stereoisomers
Isomers are compounds of the same molecular formula but different molecular structures. There are four important types of isomers. Structural isomersÂ’ atoms are bound in different orders while stereoisomers are bound in the same order but oriented differently. Geometric isomers involve different arrangement about a double bond. Optical isomers involve four groups in varying arrangements around a central atom.

Understanding the variations in the structure and composition of individual molecules with the same chemical formula.



Different types of isomers with examples



Functional Groups
Functional groups are groups of atoms in hydrocarbons which are responsible for their chemical properties. The types of functional groups include halocarbons, alcohols, ethers, aminoss, aldehydes, ketones, carboxyllic acids and esters. These functional groups are bound to a hydrocarbon structure denoted R.

Understanding how the functional groups of hydrocarbons affect their chemical properties.



Here you will find an introductory tutorial on the topic of functional groups found within organic compounds.
