Draw a resonance structure of furan that has the same number of pi bonds as the original structure. Include all lone pairs in your structure. View Submissio n HC:0

Please complete the chart below

Which of these best descibe formal charge? Select all that apply. The difference between the number of electrons around an atom in the free state and the number of electrons assigned to the atom in the Lewis structure an atom in a chemical compound. O The formal charge of each atom is calculated by subtracting the number of valence electrons in the neutral atomfrom the number of electrons assigned to the atom. O Can be used to help determine the most reasonable distribution of electrons in a molecule or ion. O The charge that an atom in a molecule or ion would have if all atoms had the same electronegativity.

Nhy is resonance structure A and resonance structure B not the same structure? If you rotate the molecule like a spicket handle (l. e. clockwise with the C at the center and the R group remaining in place as you look down the C - R bond) wouldn't you get the same thing? Why are these not equivalent structures? Resonance structure A t Resonance structure B Actual structure

central atom underlined: NH3O ICl3 XeO3 C4H4 O.R.-Lewis structure: Remember to always: • Show charge, if present. • Draw at least one more equivalent resonance structure (with «) if present, to describe delocalized covalent bonding.         count all lone pairs in LS:         polar: Y/N?

Describe the difference between a full Lewis structure and bond-line notation. What changes? Why is it easier to write?Dont

Which of the following pairs are NOT resonance structures? + H₂C-0-N=0: and H₂C-O=N-0: :0=c=0: =Ö: and :Ö= H₂C-0-N=0: and H₂C- Each of these pairs represents resonance structures. O None of these pairs represents resonance structures.

Which of these resonance structures contributes most to the overall structure of the molecule? 0=S=0 :ö-s- =s- ö-s=ö :0-s= :0::ö: :ö: :0:
