How are aliphatic aldehydes and ketones are prepared from alcohol?
Answers
Answer:
Aldehydes and ketones are generally prepared by oxidation of primary and secondary alcohols respectively. Common oxidising agents are KMnO4, K2Cr2O7 and CrO3. Strong oxidising agents oxidise the aldehyde produced by the oxidation of a primary alcohol to carboxylic acid.

Low molecular weight primary alcohols may be oxidised to aldehydes if the reaction temperature is so adjusted that the aldehyde being lower boiling then the alcohol, distils out of the reaction mixture as soon as it is formed, thus escaping from further oxidation.
