Understanding SO2 Molecular Geometry

The video tutorial explains the molecular geometry of SO2, starting with its Lewis structure, which includes a central sulfur atom bonded to two chlorine atoms and one oxygen atom, with a lone pair of electrons. The AXN notation is used to determine the molecular shape, identified as trigonal pyramidal, with bond angles of approximately 109.5 degrees. The video also provides a 3D visualization of the SO2 molecule, highlighting the arrangement of atoms and the lone pair of electrons.
