Elucidating Organic Molecules Students should be able to identify organic functional groups and recall their properties and the reactions that they undergo Properties of functional groups In additi...
Poly(alkenes) & Biodegradability Many of the polymers in use have been produced through addition polymerisation of alkenes The (poly)alkene chains are non-polar and saturated This makes them ch...
Predicting Type of Polymerisation When a set of monomers are given in an exam question, the type of polymerisation can be determined Firstly, it’s important to identify the key functional groups in...
Deducing the Repeat Unit of a Condensation Polymer In condensation polymerisation the monomers either contain 2 of the same functional group or one single monomer has both functional groups needed ...
Formation of Polyamides Amide link Polyamides are also formed using condensation polymerisation An amide link - also known as a peptide link - is the key functional group in a polyamide Monomers A ...
Formation of Polyesters Addition polymerisation has been covered in reactions of alkenes They are made using monomers that have C-C double bonds joined together to form polymers such as (poly)ethen...
