In IR spectrum, a strong peak at 1720 cm-1 indicates the presence of:
Correct answer: B. C = O Bond
- A. C = C Bond
- B. C = O Bond
- C. C ≡ N Bond
- D. O - H Bond
Explanation
The carbonyl group (C=O) exhibits a strong absorption band around 1720 cm-1 due to the stretching vibration of the double bond between the carbon and oxygen atoms.
