Chapter 2, Problem 52P

Which is a stronger acid and has the most stable conjugate base? Estimate the pKA values for both compounds.

Which cation, Q or R, do you think is the stronger acid? Why?

Rank the following compounds from most basic to least basic. Briefly explain your reasoning which may include the use of pKa values. In case you can't read them those are all negative 1 charges in the small circles. NH A B

4a.. Rank the following in order of increasing acidity: О F3C ОН F3C OH A OH B ОН 4b. Rank the following in order of increasing basicity: Ө OCH 3 NH₂ CH3CH₂CH₂CH2 с D ОН B

3. Rank the hydrogens in bold in the following molecules in order of their acidity. Rank the most acidic first down to the least acidic. I > ty > IV > 161 I H II H H III IV H

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).

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)

2. Draw the most stable conjugate base and most stable conjugate acids for the following compounds. H₂N O O O H O H OH F2 C HO CO₂H ng Provide mechanisms for the following reactions OH HO OH HO

Find which compound is the stronger base. (A) Veuillez choisir une réponse. O A OB (B)
