Why does pi bonding in Cl- give small high spin and CO give larger spin. Answer:

Question

Why does pi bonding in Cl- give small high spin and CO give larger spin.

Answer:

according to electrochemical series

Cl- is week ligand where as

CO is strong ligands

while filling the d-orbital in strong field complexes

electrons in t2g will pair up first then will go to eg orbitals

means paired electrons are more in this so this is high spin complex

whereas in case of Cl- all t2g and eg orbitals will fill with one one electrons

than it will start pair up

so less high spin

Question: What does 2tg mean? What can it possibly mean?

Explanation / Answer

in coordination chemistry

five d orbitals can split in to two set of orbitals

t2g and eg
