rarla Draw the most important resonance form to show the delocalization of charge in the ion shown below. Interactive 3D display mode CH2
1. Add curved arrows to both structures to show the delocalization of electron pairs needed to form the other resonance contributor. 2a.) Draw the predominant resonance contributor for the following compound; include lone pairs of electrons, formal charges, and hydrogen atoms. b) Add curved arrows to both structures to show the delocalization of electron pairs.
Resonance, hybridization, Lewis structures: Draw the most important resonance contributor of the 1-methylcyclohexene ion © 3 0f 15 3 of 15 Part A Draw the most important resonance contributor of the following structure. Interactive 3D display mode CH; Draw the structure on the canvas by choosing buttons from the Tools (for bonds), Atoms, and Advanced Template toolbars. The single bond is active by default.
Add curved arrows to both structures to show the delocalization of electron pairs needed to form the other resonance contributor.
7. Resonance in Organic Chemistry (22 points). A. Draw all the valid resonance forms of the ion below. At what sites can this ion react with a nucleophile? Indicate clearly with arrows.
Organic chemistry, & How many total resonance structures can be drawn for the following anion (indude those without separation charge)? How many resonance structures can be drawn for the following molecule? HANT
Add curved arrows to both resonance structures of nitromethane to show the delocalization of electron pairs. A curved arrow starts at an electron source (lone pair or bond) and points to an electron sink.
Resonance delocalization can also be used to rationalize the stability of cations (empty p-orbitals). Note that in the following series of molecules the order of stability is D<E<F. a) If the difference in stability was entirely due to the inductive effect (the polarization of bonds by electron withdrawing groups) what would be the expected order of stability of the above cations? [Hint: Draw all bond dipoles for the above molecules. Do any of the bond dipoles enhance the positive charge...
5. Resonance provides the basis for a large portion of organic chemistry and helps us identify sites of high and low electron density. We will see that the electron source (nucleophile) is attracted to the site of electron sinks or deficiency (electrophile). For the following, draw the curved arrow that shows the movement of electrons that takes you from one resonance structure to the other. Remember to always start your arrow at the source of electrons (r-bond or lone pair)....
Need clear drawing. 1) Draw the other significant resonance contributor for the following compound; include lone pairs of electrons, formal charges, and hydrogen atoms. 2) Add curved arrows to both structures to show the delocalization of electron pairs.
