Molecular Geometry of COCl2

The video tutorial explains the molecular geometry of COCl2, focusing on the central carbon atom. It starts with a valid Lewis structure and discusses the steric number, which is three due to three bonded atoms and no lone pairs. The molecular geometry is identified as trigonal planar with an ideal bond angle of 120 degrees. A 3D visualization is provided to illustrate the planar structure. The video also covers the AXE notation, confirming the trigonal planar geometry, and notes that actual bond angles differ slightly due to atom differences. The tutorial concludes with a summary of the molecular and electron geometry of COCl2.
