SATHEE: Chemical Bonding And Molecular Structure Question 373

Chemical Bonding And Molecular Structure Question 373

Question: Which of the following is paramagnetic

[DPMT 2005]

Options:

A) $N_{2}$

B) $C_{2}$

C) $N_{2}^{+}$

D) $O_{2}^{2 -}$

Show Answer

Answer:

Correct Answer: C

Solution:

$N_{2} : K K σ {(2 s)}^{2} σ * {(2 s)}^{2} π {(2 p_{x})}^{2} π {(2 p_{y})}^{2} σ {(2 p_{z})}^{2}$ (diamagnetic)

$C_{2} : K K σ {(2 s)}^{2} σ * {(2 s)}^{2} π {(2 p_{x})}^{2} π {(2 p_{y})}^{2}$ (diamagnetic)

$N_{2}^{+} : K K σ {(2 s)}^{2} σ * {(2 s)}^{2} π {(2 p_{x})}^{2} π {(2 p_{y})}^{2} σ {(2 p_{z})}^{2}$ (paramagnetic)

$O_{2}^{2 -} : K K σ {(2 s)}^{2} σ * {(2 s)}^{2} σ {(2 p_{z})}^{2} π {(2 p_{x})}^{2} π {(2 p_{y})}^{2}$ $π * {(2 p_{x})}^{2} π * {(2 p_{y})}^{2}$ (diamagnetic)
