Question

Consider the following molecules with trigonal planar geometry. Carbonate (CO32−) and nitrate (NO3−) both exhibit resonance, whereas phosgene (COCl2) does not. Given the information in the transition, and ignoring the simulation, predict the bond angles for each of the molecules in accordance to whether or not they exhibit resonance. Drag the appropriate labels to their respective targets. View Available Hint(s)\

Answer 1

Answer:

See explanation.

Explanation:

Carbonate and Nitrate: during double resonance the double bond revolves around each oxygen. This creates an atmosphere equal to each O-C-O link, then all 1200.

Phosgene: being that the atmosphere changes for each atom the bond angle should be 120, but a deviation occurs, since oxygen is more electronegative than Cl and O, so it is doubly linked. The Cl-C-O bond increases because the O and Cl repel each other, and a 124.3 bond angle is created between Cl-C-O, decreasing the Cl-C-Cl bond angle to 111.4 degrees.

See the result in the attached graph.
