Question

In both Malachite Green and Crystal Violet, the positive charge may be delocalized onto different nitrogens. Draw one structure of Crystal Violet and then show the movement of electrons that allows you to draw two other resonance structures in which there is a positive charge on nitrogen. 7. 8. Explain why Malachite Green and Crystal Violet are referred to as triarylmethane dyes.

    Question 4 (1 point) Draw the Lewis dot structures for both resonance structures of the OCBrion and then select the statement that is true. The molecule sometimes looks like one resonance structure, and at other times it looks like the other resonance structure. In one resonance structure, the carbon is in the center, and in the other one, the oxygen is in the center. The bond between carbon and oxygen would best be described as 2.5 bonds (halfway between a...

    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)....
