Isomer Definitions Flashcards
1
Q
isomer
A
- same molecular formula
- cannot turn one into the other without breaking a covalent bond
- different names and chemical properties
2
Q
structural isomer
a.k.a. constitutional isomer
A
- same molecular formula
- atoms connected to each other in a different way
- different condensed formulas
- different names and chemical properties
3
Q
functional groups isomer
A
- same molecular formula
- type of structural isomer
- belong to different families
- names have different ending/ suffix
4
Q
branch chain isomer
A
- same molecular formula
- type of structural isomer
- different backbone and/or branches
- names have different name stem/ parent and/or different names of branches
5
Q
positional isomer
A
- same molecular formula
- type of structural isomer
- same backbone/ parent and same branches/functional groups
- branches/ functional groups are attached to different carbon atoms
- only the numbers in the names are different
6
Q
stereoisomer
A
- same molecular formula
- atoms are connected to each other in the same way
- atoms are arranged differently in 3D space
- would look same if squashed flat (no 3D)
- same condensed formula
7
Q
conformer
A
- same molecular formula
- atoms connected in the same way
- same molecule, only differ by rotation around single bonds
- same condensed structure
- same name
