HYDROLYSIS

• WHAT ARE THE TYPES OF HYDROLYSIS ESTERS UNDERGO?

  1. Acid hydrolysis
  2. Base hydrolysis (saponification)
• EQUATION FOR ACID HYDROLYSIS OF ESTERS?

  ester + water (equilibrium) acid + alcohol
• WHAT DOES THE WATER ACT AS IN ACID HYDROLYSIS OF ESTERS?

  weak nucleophile
• WHY DO WATER AND ESTERS REACT?

  water acts as a nucleophile, attacking the ester on the carbonyl (slightly positive) carbon
• WHAT DOES THE ACID ACT AS IN ACID HYDROLYSIS OF ESTERS?

  catalyst

  -> affects rate equilibrium is reached
• CONDITIONS FOR ACID HYDROLYSIS OF ESTERS?

  strong acid catalyst
• EQUATION FOR SAPONIFICATION?

  ester + base -> carboxylic acid salt + alcohol
• EXAMPLE OF A BASE USED IN SAPONIFICATION?

  NaOH
• WHY IS EQUILIBRIUM NOT ESTABLISHED IN SAPONIFICATION?

  no acid
