Alcohol Flashcards
an -OH (hydroxyl) group bonded to a tetrahedral carbon atom.
Alcohol
the simplest alcohol.
Methanol, CH3OH
3 classification of alcohol
Primary, secondary, tertiary
A compound containing two -OH (hydroxyl) groups
Diol
A compound with hydroxyl (-OH) groups on adjacent carbons.
Glycol
The most important physical property of alcohols
Polarity
An Explosive and a Drug
Nitroglycerin
Discovered nitroglycerin
1847, Ascanio Sobrero
Who solved the issue with nitroglycerin by mixing it with diatomaceous earth, creating dynamite.
Alfred Nobel
Alcohols have about the same pKa values as water.
True
are weak acids and react with aqueous sodium hydroxide to form water- soluble salts
Phenols
Elimination of a molecule of water from an alcohol.
Dehydration
OH is removed from one carbon and an H is
removed from an adjacent carbon.
Dehydration
- The most difficult to dehydrate
- Generally require heating in concentrated sulfuric acid at temperature as high
as 180°C.
Primary alcohols
- ## Undergo acid-catalyzed dehydration at somewhat lower temperatures.
Secondary alcohols
