Question
The total crystal field stabilisation energy (CFSE) for the complexes [Co(H2O)6]3+ and [CoF6]3- are
respectively : (P is the pairing energy)
respectively : (P is the pairing energy)
Options
A.- 24 dq + 2P and - 24 dq + 2P
B.- 24 dq + 2P and - 4.0 dq
C.-4.0 dq and - 4.0 dq
D.-4.0 dq and 0
Solution
[Co(H2O)6]3+ diamagnetic ; CFSE = - 0.4 × 6ᐃ0 + 2P, CFSE = - 0.4 × 6 × 10dq + 2P = - 24dq + 2P [CoF6]3- paramagnetic ; CFSE = - 0.4 × 4 + 0.6 × 2 × 10dq = - 4.0 dq
ᐃO = 10 dq (arbitrary value of crystal field splitting energy)
ᐃO = 10 dq (arbitrary value of crystal field splitting energy)
