Pi-donors, Sigma-donors, and Pi-acceptors: Orbital Overlap

The video tutorial explores the spectral chemical series, focusing on the bonding between D orbitals of transition metals and ligands. It discusses weak and strong field ligands, their classification as Pi donors, Sigma donors, and Pi acceptors, and how these interact with D orbitals. The tutorial explains the significance of orbital axes in bonding, the approach of ligands along these axes, and the formation of Sigma and Pi bonds. It also introduces the concept of Pi back bonding, highlighting the electron density shift between metals and ligands.

Can a D orbital form a Sigma bond if it does not align head-to-head with a ligand? Explain.

What is π back bonding and how does it relate to π acceptors?

How do the lobes of D orbitals affect their ability to form bonds?

What is the rationale behind the bonding theories discussed in the video?
