WebSolution. Verified by Toppr. Answer. The expected answer is probably D) NO 2−. Explanation : Both O 2 and HCN also exhibit resonance but they have only one major contributor. CO 2 has two major contributors. To determine if resonance is possible, you draw the Lewis structure and then see if you can put the electrons in different locations. WebExplanation: Both CO2 and HCN also exhibit resonance, but they have only one major contributor. What is the bond polarity of HCN? HCN is an overall polar molecule with a slightly negative pole on the nitrogen atom and a slightly positive pole on the hydrogen. HCN is an overall polar molecule with a slightly negative pole on the nitrogen atom ...

WebAnswer: It does not. The lewis structure for CO_2 has two double bonds between the carbon and the oxygen. This completes the valence of 4 for the carbon. Each of the oxygen atoms has two lone pairs around it. Here’s a good picture: This structure is electron-precise; it requires no resonance. ... http://laude.cm.utexas.edu/courses/ch301/worksheet/ws4f09key.pdf sogrep abitong mackenzie foy
