Products drawn from the top to bottom of the crude oil distillation column has progressively increasing ___________________?
Correct answer: A. All A., B. and C.
- A. All A., B. and C.
- B. Molecular weight
- C. C/H ratio
- D. Boiling points
Explanation
Moving down a crude distillation column gives heavier fractions, so boiling point and molecular weight increase; their carbon-to-hydrogen ratio also generally rises. Hence all three listed trends are applicable.
