Final answer:

Alcohol conversion from alkenes to carboxylic acids, reagents, and oxidation reactions.


Explanation:

The reagent and conditions needed to convert an alkene into an alcohol:

Reagent: Acid/water or oxymercuration for more substituted alcohol, hydroboration/oxidation for less substituted alcohol.

Conditions: Vary depending on the alcohol being produced.

Conversion of ethanol into ethanoic acid: Reagent needed is an oxidizing agent like potassium dichromate or acidified potassium manganate(VII).

Type of chemical change from ethanol to ethanoic acid: Oxidation reaction.
