Concept introduction:
A resonance structure exists in species which have two or more valid Lewis structures. Resonance structures differ only in the placement of their valence electrons, not their atoms. Resonance structures are imaginary; the one, true species is represented by the resonance hybrid. A resonance hybrid is a weighted average of all resonance structures. The resonance hybrid looks most like the lowest energy (most stable) resonance structure. A resonance structure is lower in energy (i.e., more stable) with a greater number of atoms having an octet, with more covalent bonds, and with fewer atoms having a nonzero formal charge.

- For each proposed set of resonance structures: a. (E) Add curved arrows (starting from left) to show how each successive r.s. was generated. b. Cross out any resonance structures that are NOT important, and explain your reasoning.arrow_forwardClick on all structures that are identical to the first (leftmost).arrow_forwardPut the lone pairs on the following structures where appropriate and draw the curved arrows on the left-hand structures that will result in the right-hand structures.arrow_forward
- Please draw the arrow formalism on the 1st structure (top) that accounts for the 2nd resonance structure (bottom).arrow_forwardA. Draw the major resonance structure, then draw curved arrows to show how this can be converted to the Lewis structure given. B. Thionitromethane is redrawn for you. Draw curved arrows to show how this can be converted to the resonance structure you drew in part A.arrow_forwardI need to indicate how the first resonance structure (the one with #4 above it) turns into the second one with arrows, but I cannot figure it out.arrow_forward
