Study Notes

Functional Groups

  • Alcohols contain a hydroxyl group (-OH).
  • Phenols also contain a hydroxyl group attached to a benzene ring.
  • Ethers consist of an oxygen atom connected to two alkyl or aryl groups (R-O-R').

General Formula for Alcohols

  • The general formula for alcohols is CnH2n+1OH.

Characteristic Properties of Ethers

  • Ethers exhibit low reactivity compared to alcohols and can be used as solvents due to their ability to dissolve a variety of organic compounds.

IUPAC Naming of Ethers

  • The IUPAC name for the compound CH3CH2OCH2CH3 is diethyl ether.

Synthesis of Alcohols

  • A common method for synthesizing alcohols is the hydration of alkenes, where an alkene reacts with water.

Major Product from 1-Butene Reaction

  • In the reaction of 1-butene with water in the presence of a strong acid catalyst, the major product formed is 2-butanol.
