Crystal Field Stabilization Energy (CFSE) 5: Tetrahedral High-Spin

The video tutorial explains crystal field theory, focusing on tetrahedral complexes. It covers the differences between octahedral and tetrahedral complexes, emphasizing the flipped energy levels in tetrahedral complexes. The tutorial explains that tetrahedral complexes are always high spin, simplifying calculations. It demonstrates how to calculate the charge on the metal and the number of d-electrons, followed by determining the crystal field stabilization energy. The video concludes by comparing tetrahedral and octahedral complexes, highlighting the energy differences.

What is the general form of an octahedral complex?

• A metal with eight ligands and no charge

• A metal with six ligands and a charge

• A metal with four ligands and a charge

• A metal with two ligands and a charge

In a tetrahedral complex, which energy level is on top?

• Delta octahedral

• Delta tetrahedral

• T_2g

• E_g

Why are tetrahedral complexes always high spin?

• Due to the presence of delta octahedral

• Because they have less pairing energy

• Due to the inversion of energy levels

• Because they have more ligands

How is the charge on the metal in a complex determined?

• By the color of the complex

• By the overall charge of the complex

• By the type of metal

• By the number of ligands

How many d-electrons does nickel have in a Ni2+ complex?

• 10

• 8

• 6

• 4

What is the relationship between delta tetrahedral and delta octahedral?

• Delta tetrahedral is twice delta octahedral

• Delta tetrahedral is four times delta octahedral

• Delta tetrahedral is half of delta octahedral

• Delta tetrahedral is equal to delta octahedral

What is the crystal field stabilization energy for a tetrahedral complex with 8 d-electrons?

• 4/5 delta tetrahedral

• 3/5 delta tetrahedral

• 2/5 delta tetrahedral

• 1/5 delta tetrahedral
