Presentation on theme: "SUBSTITUTED HYDROCARBONS"— Presentation transcript:
1SUBSTITUTED HYDROCARBONS Objective: to learn about organic compounds which contain oxygenSubstituted Hydrocarbon: replace hydrogen atom(s) with other atoms2 Main Groups: AlcoholsOrganic Acids
2ALCOHOLS Contain a hydroxyl group (OH) in place of a hydrogen (H) atom Alcohols have a much higher boiling point than the original hydrocarbonNaming Alcohols: ends in “ol”. First, name the alkane, drop the e and add ol.
4Becomes Butanol:H H H H l l l l H – C – C – C – C - OH l l l l H H H H
5ORGANIC ACIDS O H C -OH C - H H Contain a special group of atoms called a carboxyl group: COOH in place of a methyl group (CH3 )Replace:OHC -OHC - HwithH
6Naming Organic Acids: ends in “oic acid”. First, name the alkane, drop the e, and add oic acid.
7Example Butane becomes Butanoic Acid: H H H O l l l ll H – C – C – C - C – OH l l l H H H
8A third group of substituted hydrocarbons are called Esters. Esters are formed when an alcohol reacts with an organic acid.Esters smell sweet or fruity (perfumes).
9OUTPUTDraw the one, two, and three carbon alkane, alcohol, and organic acid.You should have nine drawings altogether.Underneath each drawing, write its proper name.
10QUESTIONS How are ethane and ethanol alike? From what alkane is pentanoic acid derived?What would be the names of the alcohol and the organic acid derived from octane?Which would have a higher boiling point, nonane or nonanol?How would you know when an ester has been created?
