Question
Most oxidizing agents will turn aldehydes into carboxylic acids; ____, however, is anhydrous and is not strong enough to oxidize past the point of an aldehyde.
Answer
Most oxidizing agents will turn aldehydes into carboxylic acids; PCC, however, is anhydrous and is not strong enough to oxidize past the point of an aldehyde.
Note: When aldehydes are further oxidized, they form carboxylic acids. Any oxidizing agent stronger than PCC can perform this reaction. Some examples include potassium permanganate (KMnO4), chromium trioxide (CrO3), silver(I) oxide (Ag2O), and hydrogen peroxide (H2O2). This is shown in Figure 6.11.
