What are organic compounds?

• They are compounds that contain carbon

• Organic means “of living things”• Organic compounds can be found in

products of living things and in materials produced in labs and factories

More on organic compounds…

• They are part of the solid matter of every organism

• They are part of products made from organisms

• Example: Paper from wood of trees• Petroleum, or crude oil, is what the

raw material of what most manufactured organic compounds are made of

Properties of organic compounds

• Low melting and boiling points• Liquid or gas at room temperature• Have strong odors• Don’t conduct electric current• Don’t dissolve in water

Chemical Formulas of Chemical Formulas of HydrocarbonsHydrocarbons

• Hydrocarbons compound differ in the number of carbon and hydrogen atoms in each molecule.

• The simplest hydrocarbon is methane.• The formula for hydrocarbon is CH4.• A hydrocarbon with two carbon atoms is ethane.• Ethane is made up of 2 carbon atoms.• A hydrocarbon with 3 carbon atoms is propane.

Structure of HydrocarbonsStructure of Hydrocarbons

The carbon chains in a hydrocarbon The carbon chains in a hydrocarbon may be straight, branched, or ring-may be straight, branched, or ring-shaped.shaped.

If it has 2 or more carbon atoms, the If it has 2 or more carbon atoms, the atoms can form a single line (straight atoms can form a single line (straight chain)chain)

Alcohols and Organic Acids

By: Aly, Autumn, Brys, and Nolan

Alcohol

• An Alcohol is a substituted hydrocarbon that contains one or more hydroxyl groups

• Most alcohols dissolve well in water

• They have higher boiling points than hydrocarbons with a similar number of carbons

• Methanol is a liquid at room temperature

• Methane is a gas at room temperature

Organic Acids

• An Organic Acid is a substituted hydrocarbon that contains one or more carboxyl groups

• The carboxyl group is written as COOH

• Lemons, oranges, and grapefruits are examples of things that have organic acids in them

• Methanal

• Methane

• Vodka

• Beer

• Whiskey

• Rubbing Alcohol

The End

• There is no more slides after this one.

Esters and Polymers

By: Gabi, Campbell, Eric, Ashley, Thomas

Esters

• A compound made by chemically combining an alcohol and an organic acid.

• Many esters have pleasant fruity fragrances.

Examples of Esters!

• Bananas!

• Strawberries!

• Apples!

• Pineapples!

• Ingredients in medicine including Aspirin, anesthetic used by dentists.

Polymers

• A polymer a very large molecule that consists of smaller monomers that are a linked together in a chain.

• Organic compounds such as alcohols, esters, and others can be linked together to build polymers with thousands or even millions of atoms.

Examples of Polymers

• Wool and cotton fibers.

• Silk

• Synthetic polymers are made in factories.

• Polyester (synthetic polymer)

• Plastic (synthetic polymer)
