What are the chemical properties of alcohol?
- Alcohols are compounds that possess a hydroxyl group(OH) connected to an sp3 hybridized carbon.
- Alcohols typically have higher boiling points than that of alkanes or alkyl halides.
Boiling point of ethane: -89 C
Boiling point of Chloroethane: 12 C
Boiling point of Ethanol: 78 C
This is due to Hydrogen bonding interactions that occur between molecules of ethanol.
Alcohols are more acidic than amines and alkanes but less acidic than hydrogen halides. The pKa for most alcohols fall in the range of 15-18.
Every alcohol has two regions. The hydrophobic region does not interact well with water, while the hydrophilic region does interact with water via hydrogen bonding.
Alcohols with more than eight carbon atoms, such as nonanol and decanol, are considered to be insoluble in water.
Methanol, Ethanol, and propanol are miscible in water.
Butanol-Octonol are only soluble, meaning only a certain amount will dissolve in a specified amount of water at room temperature.
