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.
