Chemical Bonding And Molecular Structure Question 344
Question: The number of antibonding electron pairs in $ O_2^{2-} $ molecular ion on the basis of molecular orbital theory is [Pb. PMT 2000]
Options:
A) 4
B) 3
C) 2
D) 5
Show Answer
Answer:
Correct Answer: A
Solution:
$ O_2^{2-} $ consist of four antibonding electron pair [1s and 2s have two antibonding and $ 2p_{x}2p_{y} $ have two antibonding electron pair].
