MCQ
Which among the following molecules/ions is diamagnetic in nature?
  • A
    Superoxide ion
  • B
    Oxygen molecule
  • ✓
    Carbon molecule
  • D
    Unipositive ion of nitrogen molecule
✓

Answer

Correct option: C.
Carbon molecule
(c) : The electronic configuration of $C _2$ molecule is $\sigma 1 s^2 \sigma^* 1 s^2 \sigma 2 s^2 \sigma^* 2 s^2 \pi 2 p_x^2=\pi 2 p_y^2$.
Hence, it is diamagnetic in nature. Remaining given
