Chemical Bonding And Molecular Structure Question 534
Question: Among $ KO_2,,AlO_2^{-},,BaO_2 $ and $ NO_2^{+} $ unpaired electron is present in
Options:
A) $ NO_2^{+} $ and $ BaO_2 $
B) $ KO_2 $ and $ AlO_2^{-} $
C) $ KO_2 $ only
D) $ BaO_2 $ only
Show Answer
Answer:
Correct Answer: C
Solution:
Unpaired electrons are present in $ KO_2 $ while others have paired electron
$ NO_2^{+} $ = 22 electrons ; $ BaO_2 $ = 72 electrons
$ AlO_2=30 $ electrons ; $ KO_2=35 $ electrons
