Work Problem 3.27 for the reverse reactions in Fig. P3.27
Problem 3.27
(a) Classify each reaction step in the forward direction with one or more of the following terms:
(1) A Lewis acid-base reaction
(2) A Lewis acid-base association reaction
(3) A Lewis acid-base dissociation reaction
(4) An electron-pair displacement reaction
(5) A Brɸnsted acid-base reaction
(b) IF the step is a Brɸnsted acid-base reaction, indicate the conjugate acid-base pairs.
(c) Classify each species (or atoms within each species) with as many of the following terms as appropriate: nucleophile, electrophile, leaving group, Lewis acid, and/or Lewis base.
(d) Draw the curved-arrow notation for each step in the left-to-right direction. Figure P3.27
