Concept explainers
(a)
Interpretation:
All the resonance structures of the given specie are to be drawn, with curved arrows indicating which electrons are shifted. The resonance hybrid of the specie is to be drawn.
Concept introduction:
Resonance structures are alternate valid Lewis structures in which pi electrons and/or lone pair electrons are distributed in different positions. Resonance structures must follow the usual rules of Lewis structures. The connectivity of the atoms must remain the same.
The resonance hybrid is a weighted average of all resonance structures.
(b)
Interpretation:

- Draw all the reasonable resonance structures for the following which delocalizes the negative charge on different atoms. You must use electron pushing arrows notation to show the conversion of a resonance structure into another for full credit.arrow_forwardI’m not sure which formula to select. Since there is a credible bond stretch should I use the formula for alkyne?arrow_forwardDraw the resonance structure for the following molecule: Just started with resonance, where would the arrows go? I'm unsure of this problem.arrow_forward
- In HF , neither H nor F holds a full formal charge of +1 or 1 . Organic chemists represent apartial charge using the Greek letter delta () . On the electron density map of the molecule HF above, add a + to one atom and a to the other to indicate which way the bond is polarized.arrow_forwardFor each of the following compounds, identify any polar covalent bonds by indicate δ+ and δ- symbols in the appropriate locations.arrow_forwardFor the following molecule, give, according to IUPAC standards, it's name. Follow the rules for commas, spaces and dashes.arrow_forward
- could you please help me redraw this molecule and indicate all the bonds that have a dipole and the net dipole moment of the molecule, if one exists? Thank youarrow_forwardShow the other two resonance structures of the following molecule (show the curved arrows). Indicate the major contributor. Draw the resonance hybrid.arrow_forwardDraw the curved arrows and the resulting resonance structure for the following structure. Include lone pairs and charges in your structure.arrow_forward
- For the molecule shown, what orbital is the lone pair in?arrow_forwardDraw resonance structures for the following compound:Add curved arrow(s) to show resonance using one of the five patterns, and modify the second structure given to draw the new resonance structure. Include relevant formal charges in your structure. Use the + and - tools to add/remove charges to an atom, and use the single bond tool to add/remove double bonds.arrow_forwardDraw two significant resonance structures for the molecule below (start at the same site of instability for both). Only one lone pair and formal charge are provided; provide any formal charges and lone pairs that are missing on the original structure and on your resonance forms. Make sure to draw curved arrows correctly (starting from a bond/lone pair) and be very clear where the head of the arrow is pointing. Finally, rank them from most stable to least stable and justify your choices. The skeleton for your resonance is provided.arrow_forward
