IB Chemistry: Oxidation of Alcohols

This video explains how to identify different types of alcohols and how to use this information to anticipate the products formed from their oxidation. It also highlights the reagents and conditions needed to obtain a specific product.

Answers for the practice questions at the end of the video:
1. C
2. a) a hydrocarbon that contains at least one double C-C bond
b) C2H4 + H2O C2H5OH, addition/hydration reaction
c) heat under reflux; acidified potassium dichromate (VI); orange to green
d) CH3COOH + C2H5OH CH3COOCH2CH3 + H2O; sulfuric acid; ethyl ethanoate; solvent/perfumes/flavouring
3. a) Structural formula for reference CH3CH(OH)CH3
b) secondary
c) propanone
4. a) Ethanal, distil off the product; ethanoic acid, heat under reflux
b) Ethanol: -2 Ethanal: -1
c) CH3CH2OH CH3CHO + 2H+ + 2e-
d) 3CH3CH2OH + Cr2O72- + 8H+ 2Cr3+ + 3CH3CHO + 7H2O
