Resonance Structures

Q. Phosgene (Cl2CO) is a poisonous gas that was used as a chemical weapon during World War I, and it is a potential agent for chemical terrorism. Draw the Lewis structure of phosgene. Include all three resonance forms by alternating the double bond among the three terminal atoms. Draw molecules by placing atoms on the grid and connecting them with bonds. Include all nonbonding electrons.

Resonance Structures

Q. Draw the Lewis structure ( including resonance structures) for methyl azide (CH3N3). Draw the molecule by placing atoms on the canvas and connecting them with bonds. Do not identify the charge on each of these species. Include all lone pairs of electrons.

Resonance Structures

Q. For many compounds, it is possible to draw multiple Lewis dot structures that are simplifications of the structure of the true molecule. The actual structure of the molecule, called a resonance hybrid, is a combination of all the different structures, which are called resonance forms. The cyanate ion ([OCN]^-) is capale of forming three different resonance forms. Draw Lewis dot structures for the three possible resonance forms for the cyanate ion ([OCN]^-), and assign formal charges to the oxygen and nitrogen atoms in each structure. Draw all possible Lewis dot structures for the cyanate ion (OCN^-) by placing the atoms on the grid and connecting them with bonds. Include all lone pairs of electrons. Use square brackets to denote the overall charge.

Q. Based on the formal charges, draw the most preferred Lewis structure for the chlorate ion, ClO3^-. To add lone pairs, click the button before clicking on the molecule. To add bonds connect atoms with a line / . To add formal charges, click the + or - button before clicking on the molecule. Draw the molecule by placing atoms on the grid and connecting them with bonds. Include lone pairs of electrons. Use square brackets to denote the overall charge.
