- 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)The Ka of acetic acid (CH3CO2H) is 1.8x10-5 and the Kb of methylamine (CH3NH2) is 4.4x10-4. Complete the following equilibrium reaction (acid-base reaction) equation and predict the side of the equilibrium that is favored. Explain. Show all your work.Please refer to the molecule shown below when answering questions: Based on relative trends in the periodic table, which function group is more basic, II orVIII?(i) Based on relative trends in the periodic table, which function group is more acidic, II orVII?(j) Because of ring strain, this functional group is likely to undergo ring-opening uponreaction with HCl.
