Chemistry Question on Chemical bonding and molecular structure
The paramagnetic property of the oxygen molecule is due to the presence of unpaired electrons present in
A
(s2px)1and(s2px)1
B
(s2px)1and(π2py)1
C
(pi∗2px)1and(π∗2px)1
D
(pi∗2py)1and(π2py)1
Answer
(pi∗2px)1and(π∗2px)1
Explanation
Solution
The electronic configuration of oxygen molecule is as :
O2:KKs2s2,s∗2s2,s∗2sz2,π2px2≈π2py2,π∗2px1,π∗2py1
The molecule has paramagnetic character due to the presence of two unpaired electrons (π∗2px)1and(π∗2py)1.
