Which of the following statements about acetals (R-CH(OR')2) are correct?

  1. AThey do not react with in ether.
  2. BThey are stable to aqueous sodium hydroxide.
  3. CThey are cleaved to ethers by in ether at room temperature.
  4. DThey are hydrolysed by dilute aqueous acid to the aldehyde and the alcohol.

Answer: A, B, D

Acetals lack a C=O and an acidic proton, so they are inert to bases, nucleophiles and Grignard reagents. They are cleaved by aqueous acid (oxocarbenium pathway). in ether does not cleave simple acetals under normal conditions.
