  1. Question 1

    Q1. Vegetable oils remain liquid at room temperature while animal fats are solid. What structural feature of the fatty acids in oils causes this difference?

    • A) They contain more hydrogen atoms
    • B) They have only single C-C bonds
    • C) They contain one or more double bonds
    • D) They have shorter carbon chains

    Answer: They contain one or more double bonds

    Explanation: Unsaturated fatty acids contain double bonds that create kinks, preventing solidification, whereas saturated fats have only single bonds and are solid.
