Question

Isopropyl alcohol on oxidation forms:

Options

• Acetone

• Acetaldehyde

• Ether

• Methane

Answer 1

Acetone

Explanation:

Secondary alcohols are oxidized to ketones. The oxidation of isopropyl alcohol by potassium dichromate (K₂Cr₂O₇) gives acetone, the simplest ketone. Unlike aldehydes, ketones are relatively resistant to further oxidation, so no special precautions are required to isolate them as they form.
