The three-dimensional arrangement of the atoms of the molecule is molecular geometry. The molecule of sulphur dioxide is not linear in geometry. Thus, option D is correct.
Linear geometry is a type of molecular geometry that portrays the straight molecules that have a bond at 180 degrees and includes the central atom bonded to another two atoms through single or double bonds.
Carbon dioxide exhibits linear geometry as central carbon has sp hybridization and bonded to oxygen making them linear. Similarly, beryllium in beryllium fluoride and mercury in mercuric chloride are arranged linearly with their other two atoms.
Therefore, option D. sulphur dioxide does not have linear pair geometry but rather is a bent structure.
