What is organic chemistry
Chemistry of carbon compounds Often mistakes for “The chemistry of living things”
Hydrocarbon_Saturated
• Contains a C=C • Maximum number of hydrogen bond. • No change with bromine water.
Hydrocarbon_Unsaturated
• Contains one or more C=C • Room for more Hydrogen • Turns bromine water from oranges to colourless
Monomer
Single molecules
Polymer
Many molecules bonded together in a chain
Polymerisation
Monomers -> polymer
Condensation reaction
• Used to form polymers • Occurs between monomers • One molecules of water is produced every time a bond is formed. • ^ Known as Anabolism or anabolic reaction.
Hydrolysis reaction
• Used to breakdown polymers • Occurs between monomers • One molecules of water is needed to break the bond. • ^ knowns as Catabolism or catabolic reactions
Metabolism
The chemical reactions of life. Metabolism= Anabolism + Catabolism
