What Happens When Alcohols Are Oxidized?

TL;DR

The oxidation of primary alcohols converts them to aldehydes, which can further oxidize to carboxylic acids without changing the carbon count. Secondary alcohols oxidize to ketones, resulting in a loss of one carbon atom, while tertiary alcohols oxidize to ketones as well, eventually yielding carboxylic acids with a loss of two carbon atoms. Common oxidizing agents include K2Cr2O7 and sulfuric acid.

Questions & Answers

Q: What are the reagents used for the oxidation of primary alcohols?

Primary alcohols can be oxidized using an oxidizing agent, such as K2Cr2O7, in the presence of sulfuric acid.

Q: How is an aldehyde formed from the oxidation of a primary alcohol?

The oxidation of a primary alcohol produces an aldehyde and water, where the aldehyde has one fewer carbon atom compared to the original alcohol.

Q: What happens when a secondary alcohol undergoes oxidation?

Oxidation of a secondary alcohol leads to the formation of a ketone and the loss of one carbon atom due to oxidative cleavage.

Q: How is a carboxylic acid formed from a ketone?

A ketone can be further oxidized to form a carboxylic acid using an oxidizing agent like K2Cr2O7 in the presence of sulfuric acid, resulting in the loss of two carbon atoms.

Summary & Key Takeaways

• Primary alcohols can be oxidized to aldehydes using an oxidizing agent, such as K2Cr2O7 in the presence of sulfuric acid.

• Aldehydes can be further oxidized to carboxylic acids using the same oxidizing agent, resulting in no change in the number of carbon atoms.

• Secondary alcohols undergo oxidative cleavage, leading to the formation of ketones and the loss of one carbon atom.

• Tertiary alcohols can be oxidized to ketones, and further oxidation leads to the formation of carboxylic acids, resulting in the loss of two carbon atoms.
