Answer:

Answer: A. 3 mol 3 mol Al:

Explanation:

Te given balanced chemical equation is :

According to the stochiometry :

A: 3 mol 3 mol Al:

3 moles of chlorine reacts with 2 moles of aluminium

B. 2 mol 3 mol :

2 moles of aluminium reacts with 3 moles of chlorine

C. 2 mol 2 mol Al

2 mol of aluminium produces 2 mol of

D. 3 mol 2 mol

3 moles of chlorine produces with 2 moles of

Thus the conversion factor not used for mole to mole calculations is 3 mol 3 mol Al:

Ligand field diagram for octahedral complex explain briefly

stich3 [128]

The ligand field diagram for octahedral complex is explained here.

In a free metal ion, all the five d-orbitals are degenerate (i.e, having equal energies). But according to crystal field theory, under the influence of ligand field, degenracy of d-orbital is destroyed and they split into two or more energy levels. The difference in energy between two sets of d-orbitals is called Crystal Field Splitting Energy (CFSE). The extent of splitting depends upon the strength of ligand. A strong ligand causes greater splitting whereas weak ligand causes smaller splitting.

In octahedral complex, under the influence of ligand field, degenerate five d-orbitals split into two sets of orbitals -one is $t_{2g}$ and another one is $e_{g}$ . $t_{2g}$ orbital consists of $d_{xy} , d_{xz} , d_{yz}$ and $e_{g}$ orbital consists of $d_{x^{2}-y^{2} } and d_{z^{2} }$ orbitals.
