What are the resonance contributors to this ion? In drawing each additional resonance structure, use curved arrows to indicate which pairs of electrons are being shifted. Draw the resonance hybrid.
For each resonance structure, use curved arrows to show the delocalization of electron pairs that transforms the structure into the indicated resonance structure. : NH2 NH2 NH2 NH2 resonance resonance resonance resonance structure A structure B structure C structure D Do not delete any pre-drawn bonds, charges, or lone pairs. If you accidentally delete a vital part of the structure, use the undo button on the lower left of the drawing canvas.

The curved arrow notation is a powerful method used by organic chemists to show the movement of electrons not only in resonance structures, but also in chemical reactions. Since each curved arrow shows the movement of two electrons, following the curved arrows illustrates what bonds are broken and formed in a reaction. Consider the following reaction. Choose the correct image that shows the curved arrows to show the movement of electrons.
Two major resonance structures are possible for the anion shown. One resonance form is given, but it is incomplete. Complete the given structure by adding nonbonding electrons and formal charges. Draw the remaining structure, including nonbonding electrons and formal charges. Omit curved arrows. Structure A: complete the structure by adding nonbonding electrons and formal charges.

Write an equation for the reaction of CH3 SCH3 with BF3, a Lewis acid, and show by the use of curved arrows how the reaction occurs. • Show all hydrogen atoms that are not attached to a carbon atom. Apply formal charges where appropriate. Assign lone pairs and radical electrons where appropriate. • Use the "starting points" menu to revert to the original molecule(s) shown. • Draw the appropriate electron-flow arrows. • Omit+ signs between structures. ● ● CH3 | :S: | CH3 == starting points == ↑ TAYY : F کر ?
