SO₂ Bond AngleSO₂ has a bond angle of 120 degrees. Using covalent bonds, one single atom of Sulphur is bonded with the two atoms of Oxygen. It also causes a repulsion of electron pairs to form an angle of 120 degrees.SO2 Electron GeometryThe SO₂ electron geometry is formed in the trigonal planar shape. The three pairs of electron bonding will be arranged in the plane at the angle of 120-degree. As the one pair remains alone, two double pairs are bonded and thereby form a bent shape.
