  1. Question 1

    Q1. In the aromatic compound pyridine, the nitrogen atom contributes one electron to the pi-system. The hybridization state of this nitrogen atom is:

    • A) sp3
    • B) sp2
    • C) sp
    • D) dsp2

    Answer: sp2

    Explanation: In Pyridine, the nitrogen atom is sp2 hybridized. sp3 is tempting but would not allow for the delocalized pi-system in the ring.
