Multiple choice

  2. change in ratio of molecular hydrogen to carbon

  3. change in the molecular structure

  4. change in the percentage of halogen

D Correct answer
Explanation

Conversion processes in petroleum refining change carbon numbers (cracking), hydrogen-to-carbon ratios (reforming), and molecular structures (isomerization). However, halogen content is not typically altered in these processes as halogens are not naturally occurring components in crude oil that would be modified during conversion.
