HELP ASAP Sulfur dioxide (SO2) gets into the environment from burning of coal and oil. This pollutant is one of the major causes of acid rain, which is associated with the lower pH of soils, lakes, and streams and accelerated corrosion of buildings and monuments. Sulfur dioxide is also a major cause of fine particulate pollution, which is a significant health concern as well as a pollutant that reduces visibility. Given that the electronegativity of oxygen is 3.5 and that of sulfur is 2.5 and the molecule has bent geometry, which of the following best describes the chemical bonding in sulfur dioxide?

A. ionic: transfer of electrons from sulfur to oxygen

B. nonpolar covalent: equal sharing of electrons between sulfur and oxygen

C. polar covalent: electrons shared between sulfur and oxygen but attracted more to the sulfur

D. polar covalent: electrons shared between sulfur and oxygen but attracted more to the oxygen
