Chemistry: Reaction types

oxidising reaction

adding of oxygen and removal of hydrogen
substance that causes this is called oxidising agent
loss of electrons

reduction reaction

removal of oxygen and adding of hydrogen gain of electron
substance causing this is called reductant

addition reaction

moecule is broken up and insterted across:

1. a double bond forming a singl bond

2. a triple bond forming a single bond

eg. ionic addition

substitution reaction

exchanging atoms of an organic molecule for some other species
Eg. free radical substitution, formation of esters

elimination reaction

removal of water (or some other small molecule) with teh formation of a C=C double bond
Eg. formation of ethene from ethanol

condensation reaction

removal of water (or some other small molecule) with the formation of a more complex molecule
Eg. formation of ester

Hydrolysis reaction

addition of water (or some other small molecule eg. NaOH) into a compound causing it to split into two or more simpler molecules
Eg. soapification
