C/H ratio (by weight) of naphtha used in nitrogenous fertiliser making is about_________________?
Correct answer: B. 6
- A. 2
- B. 6
- C. 13
- D. 20
Explanation
Naphtha contains hydrocarbons with a typical carbon-to-hydrogen mass ratio near 6. This is higher than methane's ratio of 3 because naphtha contains heavier, less hydrogen-rich hydrocarbons.
