Question

What is the bond order of Be₂ molecule?

पर्याय

• One

• Two

• Three

• Zero

Answer 1

Zero

Explanation:

For Be₂ molecule:

(Atomic number of Be = 4)

Molecular orbital Configuration: `sigma_(1"s"^2)  sigma_(1"s"^2)^*  sigma_(2"s"^2)  sigma_(2"s"^2)^*`

Bond order = `("Bonding electrons" - "Antibonding electrons")/2`

`= (4 - 4)/2` = 0
