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 in 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


Draw:methyl phenyl ether

C-O
