1. Functional Groups http://www.ck12.org/book/CK-12-Chemistry---Second- Edition/r5/section/25.4/ Mrs Capanema

2. Alkyl Group 4 An alkyl group, generally abbreviated with the symbol R ( alkyl radical) 4 consists solely of single-bonded carbon and hydrogen atoms, for example a methyl or ethyl group.methylethyl group 4 Methyl _CH 3 Ethyl __CH 2 CH 3

3. 1. Alcohols Formula R -OH Have an O-H group. Polar molecules Dissolve in water

4. Naming Alcohols 4 In naming alcohols, the suffix “-ol” is added to the parent chain of the alkane name. Remember to start numbering the parent chain on the end closest to where the OH is located.

5. Uses CH 3 CH 2 OH ethanol

7. 2. Aldehydes 4 Have a C=O group 4 Weakily polar molecules.

8. Naming Aldehydes 4 In order to name aldehydes, use the parent chain name of the alkane and add the suffix “–al.” 4 Aldehydes have the general formula shown below.

9. Vanillin 4 Artificial vanilla flavoring is a solution of pure vanillin, usually of synthetic origin. Because of the scarcity and expense of natural vanilla extract, there has long been interest in the synthetic preparation of its predominant component.

11. 3. Carboxylic Acids 4 Have COO-H group 4 polar

12. 4 In nature, it is found in the stings and bites of many insects.stingsbitesinsects

13. Naming carboxylic acids 4 When naming organic acids, use the parent chain name of the alkane and add the suffix “–oic acid.”

14. 4. Esters 4 One oxygen is in a carbon sandwich Have you ever wondered why an orange has such a wonderful aroma, or where the smell from a freshly cut pineapple comes from? Most fruits get their rich aroma from molecules known as esters.

15. Naming esters 4 The name of an ester is composed of the name of the alkyl group from the alcohol, then of the alkyl group from the organic acid, and finally the suffix “–oate.”

16. isoamyl acetate (CH3COOC5H11) is a fundamental component of banana flavor.

17. 5. Amines 4 Polar molecules 4 Amines with low molecular weights typically have a "fishy" odor, such as cadaverine [ H2N(CH2)5NH2 ]

18. Naming Amines 4 Amines can be named by replacing the -e of the parent group with the word amine. 4 CH 3 NH CH 2 CH 3

19. 6. Ketones 4 Acetone is a common household toxic chemical that may reduce your indoor air quality after being released from such products as paint, nail polish, secondhand cigarette smoke, and many household chemical products. 4 Weakily polar

20. Naming Ketones 4 There are alkyl groups attached on both sides of the carbonyl group, therefore the molecule is a ketone. The name of this compound is 2-heptanone.

21. Ethers 4 Ether is used as a general anesthetic for surgery. 4 Slightly polar

22. Naming Ethers 4 name the alkyl groups on either side of the ether functional group and then adding the word “ether” on the end.

23. 8. Aromatics 4 The current definition of aromatic compounds includes only those with a benzene ring. 4 Benzene is also a natural part of crude oil, gasoline, and cigarette... Cigarette smoking and secondhand smoke. 4 Non polar molecules

24. Naming aromatics 4 the benzene ring has a methyl group attached. Other alkyl side-chains would be named similarly – 4 for example, methylbenzene.

25. LSD

26. Stevia
