Click the "draw structure" button to launch the drawing utility.   Draw a possible resonance structure for the molecule N2O3 (atomic arrangement is ONNO2). Show formal charges.

Draw a Lewis structure for IO4- in which the octet rule is satisfied on all atoms and show all NONZERO formal charges on all atoms. Note that the overall charge on this ion is -1.

Unshared, or lone, electron pairs play an important role in determining the chemical and physical properties of organic compounds. Thus, it is important to know which atoms carry unshared pairs.Use the structural formulas below to determine the number of unshared pairs at each designated atom.Be sure your answers are consistent with the formal charges on the formulas.

Using only single bonds, draw two corect Lewis structures of HCIO, one with Cl as the central atom and the other with O as the central atom. Calculate the formal charges of all atoms in each molecule. State which is the more likely structure based on the formal charges. In the previous problem, you drew two structures of HCIO. Are these resonance structures? Explain why or why not.

Write the Lewis symbols for boron and sulfur.

Which of the following statements concerning the structures below is/are true? Formal charges are not shown. You can select more than one, or none, of these statements. + A B On the basis of formal charges, structure B is more important than structure A. The oxidation state of N is different for each structure. In structure C, the formal charge of O is -1. Structures B and C are nonequivalent resonance structures. In structure B, the formal charge of N is +1. The total charge on this species is -1. H -NC₂=0:

Draw the Lewis structure of the hydronium ion, H3O+. Show all lone pairs and formal charges.

1. a) draw the complete Lewis structure (atoms, dots, lines, dashes, wedges, formal charges) for the formula CBr4 b) draw the complete Lewis structure (atoms, dots, lines, dashes, wedges, formal charges) for the formula NH3

Click the "draw structure" button to launch the drawing utility. Draw one of the resonance structures for the hydrogen sulfate anion  (HSO4−) . Include nonbonding electrons and formal charges where necessary. Do not draw resonance arrows.

Draw Lewis structure(s) for the carbonate lon (CO₂). If there are equivalent resonance structures, draw all of them. n D co₂2: 0 . Draw one structure per sketcher box, and separate added sketcher boxes with the symbol. Do not include overall lon charges or formal charges in your drawing. Do not draw double bonds to oxygen unless they are needed in order for the central atom to obey the octet rule. ● 6 # H Ⓒ CH, CHO: 0 Y Chemic b Draw Lewis structure(s) for the acetaldehyde molecule (CH₂CHO). If there are equivalent resonance structures, draw all of the POLICE 81 MEDITE HARA (4) Y Draw one structure per sketcher box, and separate added sketcher boxes with the symbol. Do not include overall ion charges or formal charges in your drawing. Do not draw double bonds to oxygen unless they are needed in order for the central atom to obey the octet rule.
