Q
Naming coordination complexes 
1.

5.
A
  1. Link Ligands and metals together. Ligands alphabetically. Metal last (include oxi # at end for metal)
  2. Ionic compounds with complexes is cation (space) anion
  3. Anionic Ligands- end with o
  4. Use Greek prefixes di,Tri, tetra etc. or bis,tris, tetrakis for Ligands that have prefixes in the name
  5. Anionic metal complexes- add ate to latin word for metal

Q

Geometric isomers

A

Same atoms same bond but different spatial arrangement
Cis/trans- sets of 2
Mer/fac- sets of 3

25
To check for optical/chiral/enantimer
If no plane of symmetry or is not super impossible then it is an optical/chiral
26
VB theory for CC linear

27
VB theory for CC for tetrahedral
Sp3 (d10 or d5 config)
28
VB theory for CC for square planar
dsp2 (d8 config)
29
VB theory for CC for octahedral
d2sp3 (all partially filled d)
30
Strong field
Electrons stick together Short wavelength Large delta
31
Weak field
Electrons split up Small delta Long wavelength
32
Halogens and water are
Weak field
33
Octahedral crystal field
______ _______ dz2,dx2-y2 ______ _______ _______ dxy, dyz, dxz
34
Tetrahedral crystal field
______ _______ ______ ______ ______
35
Simple cubic
CN = 6 | Atoms are 1
36
Body centered
CN=8 | Atoms are 2
37
Face centered
CN=12 | Atoms are 4
38
Mass

Alpha decay
4 He 2
40
Beta decay
0 e -1
41
Positron emssion
0 e +1
42
Nuclear decay
On products side 0 e -1
43
Joules =
Kg(m/s)^2
44
Binding energy
In kj per mol so | After finding E you have to divide by number of nucleons/atoms
45
For units that are in days or years or months
Don't round because you can't have a part of a year
46
2(Stationary lone pairs +sigma bonds)
Sigma electrons
