Organic Chemistry and Bio Chemistry CH.6 The student will investigate and understand how basic chemical properties relate to organic chemistry and biochemistry. Key concepts include  unique properties of carbon that allow multi-carbon compounds; and  uses in pharmaceuticals and genetics, petrochemicals, plastics, and food.

In order to meet this standard, it is expected that students will describe how saturation affects shape and reactivity of carbon compounds. draw Lewis dot structures, identify geometries, and describe polarities of the following molecules: CH 4, C 2 H 6, C 2 H 4, C 2 H 2, CH 3 CH 2 OH, CH 2 O, C 6 H 6, CH 3 COOH. recognize that organic compounds play a role in natural and synthetic pharmaceuticals. recognize that nucleic acids and proteins are important natural polymers. recognize that plastics formed from petrochemicals are organic compounds that consist of long chains of carbons. conduct a lab that exemplifies the versatility and importance of organic compounds (e.g., aspirin, an ester, a polymer).

What is Organic Chemistry? Organic Chemistry is the branch of chemistry concerned with the compounds of carbon: originally confined to compounds produced by living organisms but now extended to include man-made substances based on carbon, such as plastics

Why are there so many carbon containing molecules? Carbon is versatile because it can form single, double, and triple bonds. It can also form chains, branched chains, and rings when connected to other carbon atoms.
