(a)
Interpretation:
Missing curved arrows are to be supplied for the given proton transfer reaction. The relevant electrons are to be drawn if they are not shown.
Concept introduction:
In a proton transfer reaction, a proton is transferred from a Bronsted-Lowry acid to a Bronsted-Lowry base in a single elementary step in which one bond is broken and another is formed simultaneously. The curved arrow notation shows the movement of valence electrons, not atoms. The movement of two electrons is shown be using a double-barbed arrow. To represent bond breaking, the tail of the arrow originates from the center of a bond whereas to represent bond formation, the head of arrow points to an atom which forms the new bond, that is, σ bond or the region where the bond is formed if the new bond is a π bond.

For the given acid base reaction: a) Determine which is the weakest (most stable) base Show the details for your reasoning. b) Show which side of the reaction is favored at equilibrium and explain why. c) Draw the curved arrows to show the proton transfer from the acid to the base the given acid-base reaction: a) Determine which is the weakest (most stable) base. Show the details for your reasoning. b) Show which side of the reaction is favored at equilibrium and explain why c) Draw the curved arrows to show the proton transfer from the acid to the base.arrow_forwardDo all label answer to which so I know the table is there to help answer questions if neededarrow_forward
- (Intermediate) Reactant (Intermediate) Product H3C 'o: Apply Mechanism Hint Solution 2 remaining step(s) can be solved Tip: Only add curved arrows in this sketcherarrow_forwardThe following are equivalent ways of asking about the acidity of an H atom: • What is the most acidic H on the molecule? • Which H is associated with the published pKa value? • Which H on the molecule is easiest to remove? • Which H on the molecule takes the least energy to remove? • Which bond to an H is most polarized? • For which H atom is removal least uphill in energy? • Which bond to an H atom, when broken, results in the lowest PE conjugate base? We will often find the last of these questions is easiest to answer. To do this, find all the different Hatoms on the molecule, and draw all possible conjugate bases.Only the lowest-energy one is the “real” conjugate base. Identify this structure, and you have found the most acidic H. Use this strategy to find the most acidic H on each of the following molecules. Note: Each structure hasat least three different kinds of H’s, so draw at least three unique conjugate bases for each.arrow_forwardSummarize the relationship between pKa and base strength by completing the followingsentences: a. For a given base, the higher the pKa of its conjugate acid, the stronger or weaker the base. b. For a given base, the lower the pKa of its conjugate acid, the stronger or weaker the base.arrow_forward
