What is meant by the term Bond order? Calculate the bond orders in the following.
(a) `N_(2) " "` (b) `O_(2)" "` (c) `O_(2)^(+)" "` and (c) `O_(2)^(-)`

Text Solution

Verified by Experts

MO electronic configuration of `O_(2)^(+)` molecule is
`(sigma 1s)^(2)(sigma^(**)1s)^(2)(sigma2s)^(2)(sigma^(**)2s)^(2)(sigma2p_(2))^(2)`
`(pi2p_(x)^(2)pi2p_(y)^(2))(pi^(**)2p^(1))`
Bond order `=1/2[N_(b)-N_(a)]=1/2(10-5)=2.5`
