Homework Answers
The molecular structures are shown below:
Effective atomic number for each molecule
1). Na[Fe(CN)3(NH3)3]
Oxidation state of Fe=
X + 3(-1) + 3(0) = -1
X= +2
Atomic number of Fe. = 26
No. Of electrons in Fe2+=24
Electrons from 3 CN-. =6
Electrons from 3 NH3. =6
EAN. = 36(EAN is obeyed)
2). [Cr(H2O)2(NH3)2(en)]Cl3
Oxidation state of Cr=
X +2(0)+2(0)+0=+3
X=+3
Atomic number of Cr. = 24
No. Of electrons in Cr3+. = 21
Electrons from 2 H2O. = 4
Electrons from 2 NH3. =4
Electrons from en. =4
EAN. = 35(EAN not obeyed)
3). [Co (o-phen)2(NH3)(NCS)]Cl
Oxidation state of Co=
X+0+2(0)+(-1)=+1
X=+2
Atomic number of Co =27
No. Of electrons in Co2+=25
Electrons from 2 o- phen =8
Electrons from NH3 =2
Electrons from NCS=2
EAN. = 37(EAN not obeyed)
4).[(n3-C3H5)Co (CO)2]
Oxidation state of Co = 0
Atomic number of Co= 27
No. Of electrons in Co = 27
Electrons from n3-C3H5=3
Electrons from 2CO =4
EAN. =34(EAN not obeyed)
5). [Fe(diphos)(CO)3]-
Oxidation state of Fe=
X=-1
Atomic number of Fe=26
No. Of electrons in Fe-1= 27
Electrons from diphos=4
Electrons from 3 CO= 6
EAN. = 37(EAN not obeyed)
B). Kf is the rate of formation.
It is said that kf is higher for [Fe(OH-]2- than for [Zn(OH-)4 and
[Cr(OH-)4]-
In each oxidation state is given as:
Fe =+2 3d6
Zn=+2 3d10
Cr=+3 3d3
OH- is a strong field ligand and cause pairing of electrons.
In cause of Zn pairing is impossible high spin complex is formed.
Cr3+ has only 3 electrons on 3d and hence pairing occurs easily.
Fe2+ requires more pairing energy hence Kf is greater.
C). Rotation alon CH2-CH2 bond is possible so as to cause all the Nitrogens in same plane to bind the Co.
