| Question | Answer |
| what are isomers? | compounds with the same molecular formula but atoms arranged differently in space leading to different chemical or physical properties |
| types of isomerism? | structural, stereoisomers, positional, functional group and optical |
| types of structural isomers? | branched, positional or functional |
| what is a branched chain structural isomer? | carbon atoms arranged differently in chain |
| what is positional chain structural isomer? | functional groups attached to different points in main chain |
| what are functional group structural isomers? | have different functional groups |
| what are stereoisomers? | same structural formula but different spatial arrangement |
| types of stereoisomers? | geometric and optical |
| what are the types of isomers in geometric isomers? | cis (Z) and (E) trans |
| what would happen if a rotation occurred in a cis-trans isomer? | break pi bond within the double bond |
| requirements for a cis-trans isomerism? | rotation must be restricted in molecule and there must be two non-identical groups on each double bonded carbon atom |
| describe E isomer? | two high priority groups on different sides |
| describe Z isomer? | two high priority groups on the same side |
| optical isomers? | same molecular and structural formula but cannot be superimposed, where the chiral carbon is surrounded by 4 different groups |
| what are the two different forms of optical isomers called? | enantiomers |
| R chiral carbon? | clockwise direction of priority group |
| S chiral carbon? | anticlockwise direction of priority groups |
| what optical isomer form of ibuprofen is active? | S-form |
| what optical isomer of thalidomide is effective as a sedative? | R-form of thalidomide |
| what optical isomer of thalidomide causes severe birth defects? | S-form |
