Draw Lewis structure(s) for the acetate ion (CH3CO0). If there are equivalent resonance structures, draw all of them. • Draw one structure per sketcher box, and separate added sketcher boxes with the • 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. symbol. CH3C00:

a. Write a Lewis structure that obeys the octet rule for the following species. Assign the formal charge for the central atom of SO4. If multiple resonance structures exist, use one that does not involve an expanded valence. Formal charge: b. Write a Lewis structure that obeys the octet rule for the following species. Assign the formal charge for the central atom of POC13. If multiple resonance structures exist, use one that does not involve an expanded valence. Formal charge:

2. Draw the lewis structures for both resonance structures of the OCBr+ ion and select the statement that is true a. The molecule sometimes looks like one resonances structure, and at other times it looks like the other resonance structure b. In one resonance structure, the carbon is in the center, and in the other one, the oxygen is in the center c. The bond between carbon and oxygen would best be described as 2.5 bonds (halfway between a double and a triple bond) d. In one resonance structure the positive charge is on the bromine, and in the other, it is on the carbon.

What are the best steps to follow when drawing a lewis structure? I'm getting conflicting steps when determining the central atom.Do you determine it based on electronegativity or if it's the element there's only one of?

An incomplete Lewis structure is shown below. The structure only shows the atoms and how they are connected. The molecule has a net charge of zero. H Н—N—С- -о—с—Н H H Complete the Lewis structure giving all atoms full octets. If there is more than one way to do this, draw resonance structures showing all possibilities. If not, just draw one Lewis structure. Be sure to write in any non-zero formal charges. Click and drag to start drawing a structure.

Decide whether this proposed Lewis structure is reasonable. proposed Lewis structure Is the proposed Lewis structure reasonable? Yes. No, it has the wrong number of valence electrons. : Z: : 0: N O C1: The correct number is: ☐ - No, it has the right number of valence electrons but doesn't satisfy the octet rule. The symbols of the problem atoms are:* ☐ * If two or more atoms of the same element don't satisfy the octet rule, just enter the chemical symbol as many times as necessary. For example, if two oxygen atoms don't satisfy the octet rule, enter "0,0". X
