| Question | Answer |
| Alkene Functional Group | C=C |
| Alcohol Functional Group | C-OH |
| Haloalkane Functional Group | C-Haloalkane |
| Aldehyde Functional Group | CHO |
| Ketone Functional Group | CO |
| Carboxylic Acid Functional Group | COOH |
| Nitrile Functional Group | C≡N |
| Amine Functional Group | CNH2 |
| Ester Functional Group | COO |
| Amide Functional Group | CONH2 |
| Acyl Chloride Functional Group | COCl |
| Acid Anhydride Functional Group | (CO)2O |
| 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 |
