Description: In this video, we look at the oxidation of primary alcohols. First we look at what is meant by an oxidising agent. We then look at how we can oxidise a primary alcohol to an aldehyde. Then we explore how to continue the oxidation to produce a carboxylic acid and how to maximise the chances that this reaction goes to completion. 00.00 Objectives 00.12 Recap of primary, secondary and tertiary alcohols 00.36 Formation of the aldehyde 00.52 Acidified potassium dichromate as the oxidising agent 02.06 Why do aldehydes have low boiling points? 02.22 Purifying the aldehyde by distillation 02.50 Formation of the carboxylic acid 03.31 Heating under reflux 04.03 Purifying the carboxylic acid by distillation
