Jul 12, 2009 · CNO- is linear. The bond between C and N is a triple bond and a single bond exists between N and O. This arrangement will produce formal charges of 0 for C and N and -1 for oxygen, which is fine since oxygen is more electronegative. Therefore the CNO bond angle is 180 degrees. In PCl3 the Cl-P-Cl bond angle is slightly less than 109.5. C) NH3 D) N2 E) H2O. Answer: View Answer. 5) Which of the following favors the solubility of an ionic solid in a liquid solvent?
