Define Structural Isomerism same molecular formula a different structural formula
Define Chain Isomerism different arrangement of the carbon skeleton
Define Positional Isomerism the functional group changes position
Define Functional Group Isomerism the functional group changes position Alkane 》Cycloalkane Ketone 》Aldehyde
Define Stereoisomerism the same structural formula but a different arrangement in space
Types of Stereoisomerism E-Z Isomerism Optical Isomerism
E-Z Isomerism Double bonds cannot rotate (restricted rotation) Occurs when an alkene has two different atoms or groups attached
E Isomerism opposite sides
Z Isomerism same sides
Define Optical Isomerism ssme molecular and structural formula but it cannot be superimposed
Define Enantiomer two compounds that are optical isomers of eachother
Optical Isomerism + form rotates plane polarised light clockwise
Optical Isomerism - form rotates plane polarised light anticlockwise
Define Racemix Mixture contains equal quantities of each enantiomer it has no effect on plane polarised light
Define Chiral Carbon asymmetric carbon attached to 4 different grouos
Define Non-superimposable cannot be placed on top of eachother to give the same molecule
