Calorific value of ____________________?
Correct answer: C. Light paraffinic fuel oils is higher than that of equivalent olefins
- A. Light paraffinic fuel oils is equal to that of equivalent olefins
- B. n-paraffin is lower than that of iso-paraffins of the same compounds
- C. Light paraffinic fuel oils is higher than that of equivalent olefins
- D. Light paraffinic fuel oils is lower than that of equivalent olefins
Explanation
Paraffinic hydrocarbons contain more hydrogen per carbon than the corresponding olefins, so their combustion releases more heat. Therefore, light paraffinic fuel oils generally have a higher calorific value than equivalent olefinic oils.
