Concept explainers
Interpretation:
The appropriate curved arrows added to the resonance structures in solved problem 6.20 are to be shown.
Concept introduction:
In the single Lewis structure do not show the delocalization of electrons within certain molecule but resonance structure is capable of it. The delocalized electrons in molecule or ions are shown by several contributing structures. In the resonance structure, the electrons, double, triple can shift from one atom to another but the position of atom remain same. The actual structure is the average resonance structure that the possible more than one equivalent resonance structure for ions or molecule. The resonance hybrid is represented as the average of two or more equivalent structures.

- 4. An enzyme (acetoacetate decarboxylase) catalyzes the decarboxylation of acetoacetate. The mechanism has been studied extensively; concluding that the key bond-breaking step involves an enamine as a leaving group. Draw a curved arrow mechanism in the boxes below. Label the "iminium” and then "enamine" and then "iminium" as three consecutive intermediates in the mechanism. Note that the acid is stoichiometric PLUS catalytic. (Hint: acid-base involving oxygen should be drawn concerted with other steps) Enz (cat.) NH2 EnzAH EnzAH (cat.) O=U=0 Θ EnzAarrow_forwardRank the labeled H atoms in the following compound in order of increasing acidity. (See the attachment)arrow_forwardPlease answer this NEATLY, COMPLETELY, and CORRECTLY for an UPVOTE. Long and detailed explanations are not needed. Keep it short, brief, and direct because I only need the answers. Which of the following statements is (are) true about compounds A and B drawn below?arrow_forward
- Consider the below molecule and its hydrogen atoms labeled a through e. Rank the named hydrogen atoms in order of increasing acidity. Explain your choice.arrow_forwardRank the molecules in decreasing (strongest to weakest) acidity. Include ALL resonance structures with arrows and explain reasoning for rank.arrow_forward6..What is the conjugate acid of each of the following compoundsarrow_forward
- please help with all parts (a-c). I do not understandarrow_forward! ( give step by step explanation)arrow_forwardA proton transfer reaction can occur when an aldehyde is placed in strong base, such as an alkoxide ion, producing an alcohol and a charged conjugate base that is resonance stabilized. In the left box, draw the curved arrows for the proton transfer. In the middle and right boxes, draw the two structures for the resonance-stabilized product as noted in the box-specific directions. Be sure to include all lone pairs and nonzero formal charges.arrow_forward
- If possible please answer all questions. Provide a complete, detailed curved-arrow mechanism for the following reaction. Include all lone pairs and formal charges. Using the mechanism and a few words,explain the why the NaOH deprotonates at the a-position and not the b-position or the aldehyde hydrogen. Also explain why the indicated alkene is formed in the 2nd second rather than the other possible alkene product.arrow_forwardPut the following set of compounds in the increasing order of their acidity. Explain the reason why.arrow_forwardQ5. Determine whether each of the following curved arrow(s) are acceptable. For those that are, draw the products. For those that are not, explain why. (Hint: Explaining why may involve drawing the products.) (a) - HOH ? (b) :OH (c) H3N: Brarrow_forward
