Molecular Geometry of CHCl3

The video tutorial explains the molecular geometry of CHCl3 by examining its Lewis structure. It describes how the four atoms attached to the central carbon atom spread out according to the VSEPR theory. The AXN notation is used to confirm the tetrahedral geometry, which has bond angles of 109.5°. A 3D visualization of CHCl3 is provided, showing the arrangement of chlorines and hydrogen around the central carbon atom.
