Which of the folowing have identical bond orders ? .

A

`O_(2)^(Θ)`

B

`CN^(Θ)`

C

`NO^(o+)`

D

`CN^(o+)`

Text Solution

Verified by Experts

The correct Answer is:
B, C
Isoelectronic species have same bond order Number of `e^(-')s` in the following species are
(a) `O_(2)^(Θ) = 8 + 8 + 1 =17 e^(-')s`
(b) `CN^(Θ) = 6 + 7 + 1 = 14 e^(-')s`
(c ) `NO^(o+) = 7 + 8 -1 = 14 e^(-')s`
(d) `CN^(o+) = 6 + 7 - 1 =12 e^(-')s`
Hence, `CN^(Θ)` and `N_(2)` have identical bond order .
