1) These questions are concerned with the relative strengths of each molecule within a series: a) Rank the following molecules in order of descending acid strength (strongest = 1, weakest = 4) then provide a few words of explanation for your choices. HO но но но Br b) Rank the following molecules in order of descending base strength (strongest = 1, weakest = 4) then provide a few words of explanation for your choices. CH2 :NH

Complete the following table, which lists information about the measured acid dissociation constants of three unknown weak acids. Note: be sure each number you put in the table has the correct number of significant digits. acid Ka PK relative strength a x10 A ☐ 4.1 B ☐ 5.574 9 C 2.9 x 10 1 (strongest) 2 3 (weakest)

14. Consider the Bronsted-Lowry acid/base reaction below. Ⓒ acide O-H Br a. b. C. + X Br Con acide Base Con Baçe Draw the products and label the acid, base, conjugate acid, conjugate base Use curved arrows to show the movement of electrons to form the products. (Draw in missing lone pair electrons, or hydrogens if they are involved) Does equilibrium favor the starting material or products? Why? Explain your answer with structures and words. it would farver the starting as it's more stable X Why
