What are the functional groups present in the structure of maltose?

Options

  1. AOne ketal and one hemiketal
  2. BTwo acetals
  3. COne acetal and one hemiacetal
  4. DOne acetal and one ketal

Correct answer

C. One acetal and one hemiacetal

Step-by-step solution

Cyclic hemiacetal are formed when an alcohol oxygen atom adds to the carbonyl carbon of an aldehyde or a ketone. Molecules (aldehyde or ketone), which contain both an alcohol and a carbonyl group, can instead undergo an intramolecular reaction to form a cyclic hemiacetal/ hemiketal.
