Esterfication!

- Esters are formed by the reaction of a carboxylic acid and an alcohol.

Nomenclature:
- Write down the side chain without the double bonded oxygen
- Have the side chain with the double bonded oxygen end in -oate
- Standard naming rules apply.


Examples:




- Esters also have distictive fruit-like odours!

Heres a video that futher explains Esters:

Amines, Amides, and Nitro!




                                                     Amines, Amides, and Nitro!


  1. Amines are functional groups that contain a Nitrogen compound bonded to either Hydrogens and Carbons.Also, amines are alphabetically named. There are three levels of Amines:
  • - Primary Amines have 1 carbon bond
  • - Secondary Amines have 2 carbon bonds
  • - Tertiary Amines have 3 carbon bonds

Ex.
  1. Draw the following for
  • 1) ethyl methyl amine

  • 2) trimethyl amine
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Amides must have a double bonded oxygen and an NH2. The endings for Amides are "-amide".
 
One of the simplest amide is ethanamide.
 
Nitros have the funtional groupd of NO2. Also when naming a nitro, we add "Nitro" to the beginning of the name.
