Naphthenic acid is represented by ___________________?
Correct answer: B. CnH2n-2O2
- A. CnH2n+2O2
- B. CnH2n-2O2
- C. CnH2n+2O2 (n ≥ 6)
- D. CnH2n+6O2 (n ≤ 6)
Explanation
Naphthenic acids are cycloalkane carboxylic acids, so their general formula is CnH2n−2O2. The two degrees of unsaturation arise from the ring and the carboxyl group.
