7.3 Functional groups
  • Some hydrocarbons contain special groups:
  • haloalkanes , one or more halogen atoms ( F,Cl, Br,I)
  • alkanols , -OH-group
  • alkanoic acids, COOH-group, a carboxy group

Slide 5 - Tekstslide

Haloalkanes
- the carbon chain has 4-C atoms, butane
- functional group is Cl, chlorobutene
- number the carbon chain, Cl-atom attached to C-2 
                                2-chloro-butane

Slide 6 - Tekstslide

Alkanols

- three C-atoms, propane
- suffix is -ol
                                              propanol

Slide 7 - Tekstslide

alkanoic acids
- two C-atoms  : ethanoic
- suffis is placed behind the name : ethanoic acid
- the acid group has no number 
                                       ethanoic acid

Slide 8 - Tekstslide

hydrophilic and hydrophobic 
The OH-  or NH-group group can form an extra bond with the OH- group in water molecules: hydrogen bond. These substances mix well with water, hydrophilic. 



Substances with no OH-group, (halo)alkanes and alkenes do not mix with water, hydrophobic. 

Slide 9 - Tekstslide

hydrophilic and hydrophobic 
Some molecules have a hydrophilic head (OH-group) 
and a hydrophobic tail (                  ), an emulsifier
C8H17
