Chemical Bonding And Molecular Structure Question 303
Question: Which one of the following species is diamagnetic in nature-
Options:
A) $ H{e^{+}}_2 $
B) $ H_2 $
C) $ {H^{+}}_2 $
D) $ {H^{-}}_2 $
Show Answer
Answer:
Correct Answer: B
Solution:
- $ He_2^{+} $ and $ H_2^{-} $ have three electons, one must be unpaired. $ H_2^{+} $ has one unpaired electrons, whereas $ H_2 $ has two electrons and thus diamagnetic.
