Complete the equation for the reaction between each Lewis acid-base pair. In each equation, label which starting material is the Lewis acid and which is the Lewis base; use curved arrows to show the flow of electrons in each reaction. In doing this problem, it is essential that you show valence electrons for all atoms participating in each reaction. (a) (b) (c) (d)
For each molecule below, draw the conjugate acid or conjugate base or both if the molecule hasboth a conjugate acid and a conjugate base (e.g., water).
The 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.
For the previous four questions, label each molecule that appears in the question or your answer asstrong acid, strong base, weak acid, or weak base.
Summarize the relationship between pKa and acid strength by completing the following sentences: a. The higher the pKa of an acid, the stronger or weaker the acid. b. The lower the pKa of an acid, the stronger or weaker the acid.
Summarize 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.
(E) Label each of the following as strong acid, strong base, or neither.
In the reaction NH2- + CH3OH → NH3 + CH3O-, Bronsted would consider NH2- to be the (acid or base?) CH3OH to be the (acid or base?) , NH3 to be the (conjugate acid or conjugate base?) , and CH3O- to be the (conjugate acid or conjugate base?)
Rank the ions (-CH3, -NH2, HO-, and F-) from most basic to least basic.
Rank from the most basic to the most acidic
What is the weaker base, NH3 or NaNH2?
Arrange the follwoing in order of decreasing basicity. OH-, CH3COOH, CH3CH2-, NH2-, NH3, Cl- How would I solve this question? what concepts should I look into when comparing bascity? Thank You!!
