What is the product when ethanol is oxidized?

Ethanol is a primer alkohol, so the product is first an aldehyde and with further oxidation a carboxic acid.

CH3-CH2-OH --> CH3-CHO ---> CH3-COOH
ethanol acetaldehyde acetic acid

For a secunder alkohol, the product will be a ketone, and at the end carboxic acid too in the same way
R1R2CH-OH --> R1-CO-R2 ---> R1-COOH + R2-COOH

For tertiary alkohols you will obtain a mix of carboxic acides
R1R2R3C-OH ---> R1-COOH + R2-COOH + R3-COOH
