Chemical Bonding And Molecular Structure Question 345
Question: The bond order of $ He_2^{+} $ molecule ion is [Pb. PMT 2000; Pb CET 2001]
Options:
A) 1
B) 2
C) $ \frac{1}{2} $
D) $ \frac{1}{4} $
Show Answer
Answer:
Correct Answer: C
Solution:
The electron-s distribution in molecular orbitals is $ 1s^{2},,2s^{1} $ B.O. $ =\frac{2-1}{2}=\frac{1}{2}=0.5 $ .
