got 50% in the prelim. Aiming for an A... day before the exam and ive forgot what an alchohol is

Wait we DO WE need to know what an alcohol is 😭😭 ISN'T IT JUST something with OH idk

You’ll need to know the functional group of an alcohol aswell as the different types like primary, secondary, and tertiary. You’ll need to be able to identify if a molecule is one of those 3 types of alcohols and what each of those terms mean. You can also be asked what they oxidise into for example:
Primary alcohols into aldehyde and then into carboxylic acids
Secondary alcohols into ketones
Tertiary alcohols don’t oxidise into anything
Lastly they can ask how you can differentiate between an aldehyde and a ketone which there’s 3 tests for that
(Sorry that seems long I’m trynna revise by blurting )

Oh I know all this just not the definition
