Final answer:
The order of most reduced to most oxidized among the given organic molecules is as follows: hydrocarbon, alcohol, aldehyde, carboxylic acid, and carbon dioxide.
Step-by-step explanation:
In organic chemistry, the order of most reduced to most oxidized among the given organic molecules is as follows:
- Hydrocarbon: Hydrocarbons contain only carbon and hydrogen atoms and are considered to be the most reduced form of organic molecules.
- Alcohol: Alcohols have a hydroxyl group (-OH) attached to a carbon atom.
- Aldehyde: Aldehydes have a carbonyl group (C=O) at the end of a carbon chain.
- Carboxylic Acid: Carboxylic acids have a carboxyl group (-COOH) attached to a carbon atom.
- Carbon Dioxide: Carbon dioxide (CO2) is the most oxidized form, as it contains fully oxidized carbon atoms in the +4 oxidation state.
