1 of 8
Substitution reaction
One (group of) atom(s) replaces another in a molecule
2 of 8
Elimination reaction
2 atoms removed from adjacent carbon atoms in an organic molecule to produce an alkene
3 of 8
Polymerisation reaction
Thousands of monomer molecules join to form long polymeric chain
4 of 8
Hydrolysis reaction
Water splits an organic molecule into two parts (H+ & OH-), often with acid/alkali catalyst
5 of 8
Free radical
(Group of) atom(s) with an unpaired electron which uses it to form a covalent bond ; formed when a bond breaks homolytically
6 of 8
Nucleophile
Species with a lone pair of electrons which it uses to form a covalent bond ; can be anions or neutral molecules containing O or N; attack d+ centres in molecules
7 of 8
Electrophile
Attacks areas of high electron density by forming a covalent bond with a pair of electrons from the electron-rich site; can be cations, d+ atoms in molecules or neutral molecules that can be polarised
