Which of the following is true regarding the molecular geometry and the polarity for both substances? A. they are both linear because they only have two non-central atoms B. they are both polar molecules due to the polar bonds between the central atom and oxygen C. the lone pair of electrons on the S atom in SO, make it a polar bent molecule D. they are both nonpolar because the formal charge on each atom is zero 150 to 140 130arrow_forward
