structures of alcohols, carboxyclic acids and esters

  • organic molecules form the basis of living things and contain carbon atoms
  • series of molecules that have a general formula are called homologous series e.g. alkane and alkene
  • alchohols have functional group -O-H 
  • displayed formula of methanol=
  • structural formula of methanol= CH3OH
  • carboxcylic acids have functional group -COOH
  • displayed formula of ethanoic acid=(http://3.bp.blogspot.com/-FufstZ4-IpA/UiMDK0zy-II/AAAAAAAAAGM/navpF4-C6wU/s1600/Acetic_acid.png)
  • structural formula of ethanoic acid=CH3COOH
  • esters have the functional group -COO-

  • ethylethanoate structural formula=C4H8O2

properties and uses of alcohols

  • alcohols with smaller molecules such methanol and ethanol mix well with water and produce natural solutions
  • acohols are useful solvents because substances dissolve in them
  • ethanol is main alcohol in wine and beer
  • alcohols burn in air to…
