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 C-OH 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: Butyl pentyl ether C-C-C-C-O-C-C-C-C-C
