Chemical Bonding And Molecular Structure Question 315
Question: Which one is paramagnetic from the following
Options:
A) $ O_2^{-} $
B) $ NO $
C) Both A and B
D) $ C{N^{-}} $
Show Answer
Answer:
Correct Answer: C
Solution:
$ O_2^{-},(2\times 8+1=17) $ has odd number of electrons and hence it is paramagnetic. All the remaining molecules/ions, i.e., $ C{N^{-}}(6+7+1=14) $ diamagnetic $ NO(7+8=15) $ has odd number of electrons and hence it is paramagnetic.
