Question

The bond order of oxygen molecule is
a) 2.5
b) 1
c) 3
d) 2

Answer 1

The bond order of oxygen molecule is : option d -- 2

*******************************************************

Explanation :

According to Lewis theory ,
The bond order is given by the number of bonds between two atoms in a covalent molecule.

Bond order of O2=2

According to Molecular Orbital theory :

Bond order =1/2[ No. of electrons in bonding molecular orbitals - No. of electrons in Anti Bonding molecular orbits ]

Bond Order of O2= 10-6/4=4/2=2

Answer 2

Answer:

option d) 2 is correct answer
