  1. Question 1

    Q1. Which atomic property directly affects the stability of carbocation intermediates in SN1 reactions?

    • A) Electron affinity of adjacent atoms
    • B) Inductive effect of substituents
    • C) Hybridization state of the central carbon
    • D) Spin pairing of electrons in the empty p-orbital

    Answer: Hybridization state of the central carbon

    Explanation: Sp2 hybridization stabilizes positive charge through delocalization. Inductive effects and electron affinity play secondary roles.
