Which statement A-D regarding formal charge is not correct? Select one: a. Formal charge on an atom in a bond is determined by the electronegativity of that atom. b. The formal charge of an atom in a molecule is the actual charge on that atom. c. The most stable (lowest energy) Lewis structure is the one with the most formal charges equal to zero or closest to zero. d. Any negative formal charges should be on the more or most electronegative element. e. Statements A-D are all correct.

1. Indicate all formal charges in the following molecules NH2 H2N. H. H2C CH2 HO -H2 H2č. .CH2 -H ČH3

Specify the formal charges on the atoms labeled a-c in each structure. H. H a b b a .. H3C- H3C-CH2-AI- S- -- CH3 H a a b C

1. How many bonds must each of the following atoms have in order to have no formal charge? a. Carbon b. Hydrogen c. Oxygen d. Chlorine e. Nitrogen 2. Using the information from question #1, determine whether each of the following structures is possible or impossible? (Note that if no formal charges are shown, this implies that all formal charges are zero.) H H H H I MacBook Pro H H

Do I do Lewis structure 1st . Then do formal charges

Follow the curved arrows to draw a second resonance structure for each species. a. b. :o: C. -NEN: NH₂

Draw the second best resonance structure

The incomplete Lewis structure below shows all the atoms and sigma bonds for a particular molecule, but nothing else. The molecule has a net charge of +1. Fill in any missing electrons to create the best Lewis structure for the molecule. Make sure to include any non-zero formal charges. H H H. H H. H H|`H H.

Could you help me on these for question 1?

For each skeletal structure below, satisfy the valences (or octets) of all of the atoms by filling in double and triple bonds as well as unshared electron pairs. Assign non-zero formal charges and show the overall charge if the structure is an ion. H. a) H-C-N-H b) H-N-C-N-H H H H. C-H он н H. 0-C-C-N-H c) d) H-C-C -C-H H. H-C-H H. For each structure in question 4, draw a resonance hybrid (if it has one) and assign non-zero formal and/or partial charges as needed. 5. ond HICIH 4.
