(a)
Interpretation:
Resonance hybrid of the given species has to be drawn.
Concept Introduction:
Resonance hybrid is overall structure of a molecule or ion with delocalized or conjugated electrons which represents the various contributing forms of the chemical molecule or ion. Those resonance forms are also termed as canonical forms.

- A A c-) For each pair of resonance structures shown below (A and B), circle which resonance contributor makes a greater contribution to the resonance hybrid. Briefly explain your answer. O.. :0: B m N:arrow_forwardClassify the following resonance structures (a) - (c) as MOST, MAJOR and MINOR Contributor.arrow_forwardWhat are the three resonance contributors and which one is the most stable form?arrow_forward
- For the following molecules: circle the most acidic hydrogen(s). determine the approximate pKa of the hydrogen you circled rank the compounds from least (1) to most (5) acidic compound.arrow_forwardWrite an additional resonance contributing structure for each carbocation and state which of the two makes the greater contribution to the resonance hybrid. Classify each additional contributing structure as a 1°, 2°, or 3° allylic cationarrow_forwardLabel each double bond E, Z, or neither. (It may help to draw in some missing H’s.)arrow_forward
- Could you explain why the highlighted group on the right side of the double bond has a higher priority than the lower group on the right side of the double bond. I use this information to determine E/Z assigmentsarrow_forwardGiven below are the most important resonance structures for ethyl cinnamate and the product. a) For ethyl cinnamate, draw the next two most favorable resonance structures (ignore resonance with the aromatic ring): 0? b) For your hydrogenation product, draw one more favorable resonance structure:arrow_forwardOne of the following structures for nitrobenzene is not a significant resonance contributor. Circle the structure that is not a significant resonance contributor.arrow_forward
