a) Electron Geometry: The electron geometry of SO2 is trigonal planar. This is because sulfur dioxide has three regions of electron density around the central sulfur atom: two bonding pairs (with oxygen atoms) and one lone pair.
b) Molecular Geometry Shape: The molecular geometry shape of SO2 is bent or V-shaped. This is due to the presence of one lone pair on the sulfur atom, which causes the bond angles to be less than 120 degrees, resulting in a bent shape.
c) Is the Molecule Symmetrical or Asymmetrical: The SO2 molecule is asymmetrical. The presence of the lone pair on the sulfur atom and the bent shape make the molecule asymmetrical.
d) Is the Molecule Polar or Nonpolar: The SO2 molecule is polar. The asymmetrical shape and the difference in electronegativity between sulfur and oxygen create a dipole moment, making the molecule polar.
