Molecular Geometry of ICl4-

The video tutorial explores the molecular geometry of ICl4- by first examining its Lewis structure. It explains how the chlorine atoms and lone pairs around the central iodine atom influence the molecular geometry, resulting in a square planar shape. The tutorial also discusses the electron geometry, which is octahedral, and introduces the concepts of steric number and AXE notation to further understand the molecular structure. The bond angles are highlighted, and the video concludes with a summary of the key points.
