Oxidation of alcohols




AQA Content

Write equations for these oxidation reactions (equations showing [O] as oxidant are acceptable)
Explain how the method used to oxidise a primary alcohol determines whether an aldehyde or carboxylic acid is obtained
Use chemical tests to distinguish between aldehydes and ketones including Fehling’s solution and Tollens’ reagent.

Specification Notes

Alcohols are classified as primary, secondary and tertiary.
Primary alcohols can be oxidised to aldehydes which can be further oxidised to carboxylic acids.
Secondary alcohols can be oxidised to ketones.
Tertiary alcohols are not easily oxidised.
Acidified potassium dichromate(VI) is a suitable oxidising agent.
