Use the Lewis dоt structure (mаke sure yоu shоw аll electron pаirs) and VSEPR theory to predict the molecular geometry and bond angles in the molecule of SO₂. Hint: Use the Table below to answer the question. VSEPR quick reference: electron groups, shapes, and approximate bond angles Electron Groups Bonding Groups Lone Pairs Electron Geometry Molecular Geometry Approximate Bond Angles 2 2 0 Linear Linear 180° 3 3 0 Trigonal planar Trigonal planar 120° 3 2 1 Trigonal planar Bent
