The bond order for a species with the configuration, `sigma1s^(2), sigma^(**)1s^(2), sigma 2s^(2), sigma^(**)s^(2), pi2p_(x)^(1)` will be

A

`1`

B

`(1)/(2)`

C

zero

D

`1`

Text Solution

Verified by Experts

The correct Answer is:
B
`sigma1s^(2) sigma^(**)1s^(2) sigma2s^(2) sigma^(**)2s^(2) sigma2p_(z)^(1)`
Bond order `=(1)/(2)[N_(b)-N_a] =(1)/(2)[5-4]=(1)/(2)`.
