IB DP Chemistry: SL复习笔记10.1.6 Organic Families - Alcohols & Ethers

Alcohols & Ethers

Alcohols

  • Alcohols are a family of molecules that contain the hydroxyl functional group-OH
  • Their general formula is  CnH2n+1OH
  • The nomenclature of alcohols follows the pattern alkan + ol
  • If there are two -OH groups present the molecule is called a diol

The first four Alcohols and their Structures Table

Classification of alcohols

  • Alcohols are classified as primary, secondary or tertiary depending on the number of carbons attached to the functional group carbon
  • This is covered in detail in Section 10.1.11

Ethers

  • Ethers are a family of molecules that contain the ether functional groupR-O-R, where R is an alkyl group
  • Their general formula is  CnH2n+2
  • The nomenclature of ether follows the pattern alkoxy + alkane
  • Sometimes you will see an older nomenclature for ethers where each R group is given an alkyl name
    • For Example: CH3OCH3 is dimethyl ether and C2H5OCHis ethyl methyl ether
  • Ethers are functional group isomers of alcohols
