Question:

L-Ascorbic acid (vitamin C) has the following structure: . H HO CHOH -0- or 0=0 -- - H- CHOH

(a) Ascorbic acid has pK_a = 4.21, and is thus about as acidic as a typical carboxylic acid. Identify the acidic hydrogen and explain.

(b) Thousands of tons annually of ascorbic acid are made commercially from d-glucose. In the synthesis shown in Fig. P24.60, give the structures of the compounds A–C.
