Questions & Step-by-Step Solutions

What is the main product when propanal is treated with excess alcohol in the presence of an acid catalyst?
  • Step 1: Start with propanal, which is an aldehyde.
  • Step 2: Add excess alcohol to the propanal.
  • Step 3: Introduce an acid catalyst to the mixture. This helps the reaction occur.
  • Step 4: The alcohol reacts with the propanal to form a hemiacetal first.
  • Step 5: Since there is excess alcohol, the hemiacetal can further react.
  • Step 6: The final product is an acetal, which is formed when the hemiacetal reacts with more alcohol.
