  1. Question 1

    Q1. Graphite conducts electricity while Diamond acts as an insulator. This contrast in electrical conductivity is primarily due to the fact that:

    • A) Diamond is sp2 hybridized
    • B) Graphite is sp2 hybridized with delocalized electrons
    • C) Graphite is sp3 hybridized
    • D) Diamond has delocalized pi electrons

    Answer: Graphite is sp2 hybridized with delocalized electrons

    Explanation: Graphite uses sp2 hybridization leaving one free electron for conduction, while Diamond uses sp3 with all electrons localized in bonds.
