Organic Compounds
Compounds are divided in to two – Organic and Inorganic
Organic Compounds –
Originate from living things
They are easily decomposed
They are the main component of most of our fuels such as gasoline, oil and natural gas

2. Organic Compounds
They are also the active ingredient in pharmaceuticals such as aspirin and ibuprofen
Organic compounds are composed of C and H and also include a few other elements such as N,S and O.
The simplest organic compound is CH4

3. Chemistry of Carbon
The chemistry of Carbon is unique and complex because carbon frequently bond to itself to form chain branched and ring structures Carbon also forms double and triple bonds with itself and other elements

4. Propane

5. Isobutane -C4H10

6. Cyclohexane – C6H12

7. Ethene -C2H4

8. Ethyne -C2H2

9. Acetic Acid - CH3 -COOH

10. Organic compounds - Classification
Organic compounds are classified in to Hydrocarbons and functionalized hydrocarbons
Hydrocarbons are organic compounds that contains only carbon and hydrogen. Hydrocarbon containing only single bond are called alkanes while those containing double or triple bonds are alkenes are alkynes

11. Classification of Organic compounds

12. The names of simple straight chain hydrocarbons consist of a base name which is determined by the number of carbon atoms in the chain and a suffix determined by whether the hydrocarbon is an alkane(-ane) alkene(-ene) or alkyne(-yne)
Base name determined by the number of Carbon atoms
Suffix determined by the number of multiple bonds

13. The base names for a number of hydrocarbons are listed
Meth = 1 Hept = 7 Eth = 2 Oct = 8 Prop = 3 non = 9 But = 4 dec = 10 Pent = 5 Hex = 6

15. Functionalized Hydrocarbons
They are hydrocarbons with functional groups
Example: Alcohols have –OH as functional group
They have the general formula R-OH
Where R represents the hydrocarbon portion of the molecule
Methanol, Ethanol, and propanol belongs to the same family.

16. Methanol - CH3-OH Ethanol - CH3-CH2-OH Propanol - CH3-CH-OH CH3
The addition of functional group to hydrocarbon usually alters the property of the compound
Methanol - CH3-OH
Ethanol - CH3-CH2-OH
Propanol - CH3-CH-OH
CH3
