  1. Question 1

    Q1. A chemical engineer uses reforming instead of cracking to treat a naphtha fraction. What is the primary structural change achieved through reforming?

    • A) Reforming decreases the octane number of gasoline
    • B) Reforming involves the thermal decomposition of large alkanes
    • C) Reforming converts straight chains into branched chains
    • D) Reforming is used to produce kerosene from heavy oil

    Answer: Reforming converts straight chains into branched chains

    Explanation: Reforming converts straight-chain alkanes into branched-chain or aromatic hydrocarbons to improve fuel quality, whereas cracking breaks large molecules into smaller ones.
