How are polymers formed
Through small molecules called monomers
What are polymers?
Very large molecules made up of a backbone of dominating carbon chains
What is addition polymerisation
Alkenes joining together to form polymers
What are condensation polymers?
Formed between monomers that each have two reactive groups , the polymer is formed together with water
What is the saponification rxn?
Process in which soap is made by which an oil or fat is boiled with NaOH or KOH solution (Lye)
How do soaps and detergents act as cleaning agents?
Charged end of the surfactant ion dissolves in the polar solvent (water) while the non-polar hydrocarbon chain dissolves onto the non-polar grease, oil or dirt
Why are detergents sometimes used instead of soap?
Soap doesn’t function in hard water as the surfactant ion precipitates out with the calcium and magnesium ions in the water. Detergents don’t due to their sulfate group and functions in all types of water
