New cards
complex ions
In naming ________ or molecules, the ligands are named before the metal.
2
New cards
Bidentate
________: a chelate that can donate 2 electron pairs.
3
New cards
Brackets
________ are used to set off the complex ion from the remainder of a given compound.
4
New cards
Coordination sphere
________ isomers: structural isomers that differ in what ligands are bound to the metal and which fall outside the ________.
5
New cards
Chelates
________: ligands that can donate 2 or more electron pairs.
6
New cards
Optical isomers
________, or enantiomers: stereoisomers that are non- superimposable mirror images of one another.
7
New cards
Ligand
________: Lewis bases bounded to /surrounding the central ion.
8
New cards
Coordinate covalent bond
________: one in which both shared electrons come from the same atom.
9
New cards
Central ion
________: center of coordination compound; ion that all surrounding atoms are bound to.
10
New cards
Isomers
________: the same molecular formula but a different arrangement of atoms.
11
New cards
Coordination sphere
________: the part of the compound that is in the bracket.
12
New cards
Central ion
center of coordination compound; ion that all surrounding atoms are bound to
13
New cards
Ligand
Lewis bases bounded to/surrounding the central ion
14
New cards
Coordinate covalent bond
one in which both shared electrons come from the same atom
15
New cards
Coordination number
the number of electron pairs gained by the central ion
16
New cards
Coordination sphere
the part of the compound that is in the bracket
17
New cards
Chelates
ligands that can donate 2 or more electron pairs
18
New cards
Bidentate
a chelate that can donate 2 electron pairs
19
New cards
Isomers
the same molecular formula but a different arrangement of atoms
20
New cards
There are two main subgroupings
structural isomers and stereoisomers
21
New cards
Linkage isomers
at type of structural isomer where the ligand is bound to the metal by a different atom
22
New cards
Coordination sphere isomers
structural isomers that differ in what ligands are bound to the metal and which fall outside the coordination sphere
23
New cards
Geometric isomers
stereoisomers in which the ligands have a different spatial relationship
24
New cards
Optical isomers, or enantiomers
stereoisomers that are non-superimposable mirror images of one another
