(a) Outline two features of this experiment that ensure that the propanal intermediate is not a major product.
Oxidation of alcohols
Write equations for the oxidation of primary alcohols to aldehydes and then carboxylic acids and of secondary alcohols to ketones with acidified dichromate(VI), explain why tertiary alcohols resist oxidation, and relate distillation versus reflux to the product obtained.
