Esterification of Alcohols using an Acid Anhydride

• Derivatives of carboxylic acids

• Much faster

• Reacts completely on warming

  • Higher yield of ester

• Eg.

\[\textup{Ethanoic Anhydride}+\textup{Ethanol}\Rightarrow \textup{Ethyl Ethanoate} + \textup{Ethanoic Acid}\]

Ethers

• -\(O\)-

• Structural isomers of alcohols

• Derived from alkanes

  • Substitution of \(H\) for -\(OR\), alkoxy group
