  1. Question 1

    Q1. A molecule of benzene (C6H6) contains a delocalized system. Calculate the ratio of total sigma bonds to total pi bonds in one molecule.

    • A) 1:1
    • B) 2:1
    • C) 3:1
    • D) 4:1

    Answer: 4:1

    Explanation: Benzene has 12 sigma bonds (6 C-C, 6 C-H) and 3 pi bonds; the ratio 12:3 simplifies to 4:1. 2:1 ignores the C-H sigma bonds.
