Why does acetone [(CH3)2C=O, dipole moment = 2.69 D] have a larger dipole moment than phosgene [Cl₂C=O, dipole moment = 1.17 D]? Note: electronegativities C = 2.5, Cl = 3.2, O = 3.5, H = 2.2 Select one: O A. In phosgene, the resultant of the C-Cl bond dipole moments is opposite to and partially cancels the C=O dipole moment. In acetone, the resultant of the C-H bond dipole moments (although small) adds to the C=O dipole moment. O B. Phosgene has a tetrahedral geometry while acetone possesses a trigonal geometry. OC. The C-H bond dipole moments of acetone are greater in magnitude than C-Cl bond dipole moments of phosgene. O D. In phosgene the C-Cl bond dipoles cancel out each other.
