Other Organic Compounds(p. 29) Functional Group Atom or group of atoms that give specific properties to an organic compound. Same functional group Similar properties Classified together

Alcohols  Organic compound that contains one or more hydroxyl group (-OH); the oxygen is bonded to a hydrogen and a carbon.  General formula: R-OH

Naming Alcohols:  If no number is present in front of the parent name, presume the –OH is on carbon number 1.  If 1 –OH group  Drop the “e” on the parent name and add “ol”. Example: C-C-C-C-OH 1-butanol

Example C-C-C-C-C-C-C OH 3-heptanol

Name: C C-C-C-C- C OH 2-methyl-2-pentanol

Naming alcohols continued If two or more –OH groups 2= -diol 3=-triol 4= tetraol Keep the –ane, add the appropriate ending listed above.

Example: C-OH 1,2,3-propanetriol

Draw: 1, 2, 4, 5-pentanetetraol OH OH C-C-C-C-C OH OH

Ethers  Organic compounds with 2 hydrocarbons bonded to the same oxygen  General formula: R-O-R’  Where R and R’ can be the same size or different.

Naming Ethers:  Arrange the R and R’ groups on alphabetical order.  Use –yl endings like branches; if R and R’ are the same, use “di”.  End the name with the word ether.

Name: C-C-O-C-C-C-C Butyl ethyl ether

Name: C-C-C-O-C-C-C dipropyl ether

Name: C-C-C-O-C methyl propyl ether

Draw: Dicyclohexyl ether
