The number of antibonding electron pairs in o2

Asked by admin @ in Chemistry viewed by 307 People

The number of anti-bonding electron pairs in o2- molecular ion on the basis of molecular orbital theory is (atomic no. of is8) :

options are: a)5 b)2 c)3 d)6

Answered by admin @


Answer:

\bold {7}

Explanation:

After oxygen, molecular orbital diagram becomes symmetrical due to pairing of electrons in the p-orbital which cause inter-electronic repulsion by which σ 2p(z) jump over π2p(x) and π2p(y). Hence, molecular orbital diagram becomes symmetrical!

The number of bonding e- pairs in O²- : 10

The number of anti-bonding e- pairs in O²- : \bold{ 7 }

• Now , ½ [ N(b) - N(a) ]

• ½ [ 10-7 ]

• ½ [3]

• 1.5

•||The above attachment is having M.O.D of O2||•

Hope it helps!
