Feb 11 Organic Chemistry
Transcript of Feb 11 Organic Chemistry
Carbon can make a maximum of four bonds, but it may take different forms, called allotropes:
1. Soot (amorphous/unlinked carbon)
2. Graphene (theoretical single 2D sheet of carbon)
3. Graphite (3 sheets of graphene linked in 3D
How Does this Relate to my Dish Soap?
The commercial definition of organic is troublesome. Why might this be? What do you think organic means?
Time to Investigate!
Part 1: In groups of two or three, investigate at least five products.
Determine the functional group and decide whether you believe it is green or not.
Part 2: Compare one green and one normal product by its ingredients, and answer the questions at the bottom of the page
Organic = Carbon?
"Organic? Like my dish soap?"
Organic molecules can also contain...
"Organic like my dish soap?" - History and meaning of organic chemistry + research project
The Hydrocarbons: Like a Family, Except not People - The family of hydrogen and carbon-only molecules
Alkanes, alkenes, alkynes and cyclic hydrocarbons
Aldehydes, alkyl halides, alcohols, carboxylic acids, ketones, ethers, esters, amines, amides
The History of Organic Chemistry
Chemists in the 19th century (1800s) were described in two ways:
Part of a plant or animal that was alive or that had once been alive
Any substance produced by a plant or animal
They believed that a 'vital force' was required to create an organic compound, and humans could not create this required vital force
A Few Exceptions Exist
Although all organic compounds contain carbon, not all carbon compounds are organic.
Please have your 'What IS Organic' worksheet completed for collection Thursday morning
Topic for Thursday - The Hydrocarbons: Like a Family, Except not People.
The End Goal
In groups of 3, you will research and present on a particular polymer
The definition of organic in terms of chemistry is separate from the definition we think of at the grocery store. In fact, the definition has changed even within the field of chemistry.
What caused the change? Why, using
the scientific method
The Modern Definition
What all the molecules shared was the presence of carbon, which became the basis for the new definition of an organic molecule. Therefore, by our definition:
ALL ORGANIC COMPOUNDS CONTAIN CARBON!
