Concept explainers
(a)
Interpretation: Categorization of resonance structures as “Equivalent” and “Not equivalent” resonance structure for the bases mentioned below should be determined.
Concept introduction: When one single structure is unable to describe all the properties of single molecule, a phenomenon called resonance comes into play. This arises when two or more than two Lewis structures are possible for one molecule. All such structures are called resonating structures and have same placement of atoms in them but these have different locations of bond pairs and lone pairs. The resonating structures are inter-convertible with each other. The resultant of all the resonating or contributing structures is called the resonance hybrid.
(b)
Interpretation: Resonance structure in base mentioned below that has lowest potential energy should be determined.

Organic Chemistry: A Guided Inquiry
- a. Which of the following has a greater electronegativity? (circle one) Carbon / Cesium b. Explain why you chose your answer in Za.arrow_forwardI had gotten this one incorrect, but i wanted to use it to study, so please give me the solution to all parts of this question.arrow_forwardHelp! a.) Draw all the important resonance contributors for the structure shown below. Use curved arrows to show the movement of electrons between these contributors. b.) Draw the hybrid resonance hybrid structure.arrow_forward
- 9. The two molecules shown below are structurally very similar. Draw all resonance structure for each species with curved arrows and circle which is molecule (A or B) is more stable because it has more resonance structures. Only use patterns 2 and 3. A Barrow_forwardExplain it mildly and simple?arrow_forward2. Each resonance structure of a given molecule contributes to the resonance hybrid. The more stable the resonance structure, the more that resonance structure contributes to the resonance hybrid. For the following resonance structures, a. Circle the resonance structure that contributes most to the resonance hybrid. b. Explain your choice for a in complete sentences. c. Draw the resonance hybrid. d. Add curved arrows to indicate the flow of electrons in each structure except the D. H A Q Search B hyji C Darrow_forward
- Rank the following radicals in order of energy (most to least).arrow_forward2. Tetrahydrocannabinolic acid (THCA), the precursor to THC, a psvchoactive: H.. • This molecule is missing eight lone pairs. Add them to the structure above • Check the formal charges of the oxygen atoms above. Do any of them have a non-zero formal charge? If so, add the charges to the appropriate oxygen atoms • THCA is a weak acid. Identify and circle the acidic hydrogen on the above structure • Draw a resonance structure of this molecule belowarrow_forwardA. Determine whether the curved arrow(s) shown below generate a valid or invalid resonance structure. Draw the resonance structure that would result from each properly drawn arrow and identify the arrow pushing pattern (i.e. allylic positive charge, allylic lone pair, pi bond between atoms of a different electronegativity, lone pair adjacent to a positive charge, alternating pi bonds in a ring.arrow_forward
- Solve correctly please. Should 100% sure of final answer with some explanation of them.arrow_forwardDraw both resonance structures of the anion formed by the reaction of the most acidic C-H bond of the compound below with base. a Include all valence lone pairs in your answer. . For structures having different hydrogens of comparable acidity, assume that the reaction occurs at the less-substituted carbon • Draw one structure per sketcher. Add additional sketchers using the drop-down menu in the bottom right corner. Separate resonance structures using the symbol from the drop-down menu. . O CParrow_forwardCriteria for success All molecular drawings must be valid Lewis structures (octet rule, formal charge, valence, geometry). Curved arrows will be interpreted very strictly. Thus, they must clearly indicate the origin and destination of electron delocalization. Tasks 1. Generate at least three reasonable resonance contributors of the molecule in Fig. 3. 2. Rank reasonance contributors from least significant to most significant (#1 = most significant) and explain your choice. 3. For highlighted nitrogen atom indicate if the lone pair of electrons is localized or delocalized. Briefly explain. NH₂ Figure 3: Molecule with delocalized electrons Zarrow_forward
