[11.4] isomerism Flashcards
1
Q
what is isomerism?
A
different molecules with the same molecular formula are known as isomers
2
Q
what are structural isomers?
A
molecules with the same molecular formula but a different structure
3
Q
what are 3 types of structural isomers?
A
- chain isomers
- position isomers
- functional isomers
4
Q
what are chain isomers?
A
- caused by different arrangement of the carbon skeleton
- similar chemical properties (same functional group)
- slightly different physical properties
- more branching = lower boiling point
5
Q
what are position isomers?
A
- molecule has the same carbon skeleton
- molecule has the same function group but the functional group is in a different position
- similar chemical properties
- different physical properties
6
Q
what are functional isomers?
A
- molecules have the same molecular formula
- molecules have different functional groups
- different chemical properties
- different physical properties
