Decide whether each row is a set of resonance structures for a single molecule and select "yes" or "no" in the last column. N structures resonance structures? 'N yes Н HIN H-V ¿ Н مد لله no ○ yes no ○ yes no ○ yes no

Q/ Three resonance structures of the highly unstable CSN – ion are shown below. a) Label any and all atomic formal charges that are present in each structure. b) Which of the structures is the major resonance structure? Why?

None

Which of the following species is not a resonance structure of the top species?

The following is a skeleton of a molecular anion having the overall formula C7H6NO–. The H atoms are not shown. Starting with the structure drawn below, complete the Lewis structure by adding all H atoms, valence electrons, and π bonds. This structure will have a –1 formal charge on the oxygen.

What are the formal charges for the indicated atoms in the neutral structure below くーG C=N,=N2 OC = 0, N1=-1, N2 = +1 OC = 0, N1 = 0, N2 = 0 %3D OC = 0, N1 = +1, N2 = – 1 OC = -1, N = +1, N2 = 0

Which of the following resonance structures is the most stable? || I ||| ON II III ∞-∞ IV N V

Should 100% sure of answer. Draw the Lewis structure of HBrO₃ (by following the octet rule on all atoms) and then choose the appropriate pair of molecular geometries of the two central atoms. Your answer choice is independent of the orientation of your drawn structure.

What are the resonance structures of this molecule? Does each transition have one or two arrows?

Why are the major structures the ones where carbon has incomplete octets? Isn't the first rule for major resonance structures that the structure have as many full octets as possible?
