Answer 2

CH₃CH₂OH can be converted into CH₃CHO by treatment with pyridinium chlorochromate.

Explanation:

Pyridinium chlorochromate (PCC)

• It is a yellow-orange salt.
• Organic synthesis is a reagent.
• It is used as oxidation of alcohols for the formation of carbonyls.
• It is greatly effective in oxidizing primary alcohols and secondary alcohols to ketones and aldehydes.
• The formation of PCC is between chromium trioxide, pyridine, and hydrochloric acid.
• Addition of one equivalent of PCC in the primary alcohol to produce aldehydes and the byproducts are chromium and Pyridinium hydrochloride.
• The amount of $H{2} O$ present in this reaction should be conscious.
• The presence of water, the aldehyde can make the further reactions.
