Answer Details
When ethanol is progressively oxidized to ethanoic acid with potassium heptaoxodichromate (IV), the intermediate product formed is ethanal. This is because ethanol is first oxidized to acetaldehyde (ethanal) before further oxidation to ethanoic acid. Acetaldehyde is an intermediate product in the oxidation of ethanol to ethanoic acid. Therefore, the correct option is "ethanal".
