Question
- A. Alcohol
- B. Aldehyde
- C. Carboxylic acid
- D. Ketone
Answer
Ketone
Explanation
The evidence shows that a strong absorption peak around 1700 cm⁻¹ is characteristic of the C=O bond found in ketones. This implies that the presence of this peak indicates the functional group is likely a ketone. Therefore, the correct identification of the functional group is a ketone.
Common mistake
Misidentifying Functional Groups
Students often confuse the absorption peaks in infrared spectra, leading to incorrect identification of functional groups.
To fix this, students should carefully study the characteristic absorption ranges for different functional groups and practice interpreting spectra with reference materials.
