Organic Chemistry (April 30, 2010)

What is organic chemistry? For starters, it is the study of carbon compounds. Also, know that carbon can have multiple bonds and form many different things.

What are the 3 types of hydrocarbons? Alicyclics, aromatics and aliphatics are 3 types of hydrocarbons. However, Alkanes, alkenes and alkynes all fall under the category of aliphatics.

What are the 3 types of formla's for hydrocarbons?
1)Molecular formulas (Example: C6H14)
2) Condensed Structural formula (Example: CH3 - CH2 - CH2 - CH2 - CH2- CH3)
3) Structural Formula

Describe a characteristic of the nomenclature of hydrocarbons. Only one molecular formula can have a number of different structures. Also, isomers are compounds that can be drawn in more than one way.
Example: butane C4H10 CH3 - CH2 - CH2 - CH3

How do you name Alkanes (that all have single bonds)?
1) Name the longest chain by using the correct suffix and adding "ane"
2) Locate any branches by numbering carbon atoms. (*Use the lowest possible number system*)
3) Name branches by using appropriate suffix and -yl ending (alkyl branches)
4) If there are more than one of the same alkyl group, number each one and add the multiplier number in front of the branch name.

Examples:
Below is a picture of a chart that includes the number of carbon atoms, stem name, side chain (Alkyl group) name, and the multiplier. It will help you very much when naming hydrocarbons.

  1. I’m going to read this. I’ll be sure to come back. thanks for sharing. and also This article gives the light in which we can observe the reality. this is very nice one and gives indepth information. thanks for this nice article... organic formula
