1.	Which of the following pairs of species have the same bond order-
Answer» `O_(2),NO^(+)` `CN^(-),CO` `N_(2),O_(2)^(+)` `CO,NO` Solution :TOTAL no. of electrons PRESENT in `CN^(-)=14` Total no. of electrons present in `CO=14` MO electronic configuration of `CO-` `(sigma_(1s))^(2)(sigma_(1s)^())^(2)(sigma_(2s))^(2)(sigma_(2p_(z)))^(2)(sigma_(2s)^())^(2)(pi_(2p_(X)))^(2)(pi_(2p_(y)))^(2)` MO electronic configuration of `CN^(-)`- `(sigma_(1s))^(2)(sigma_(1s)^())^(2)(sigma_(2s))^(2)(sigma_(2s)^())^(2)(pi_(2p_(x)))^(2)(pi_(2p_(y)))^(2)(sigma_(2p_(z)))^(2)` ltbgt bond order of `CO=(1)/(2)(8-2)=3` Bond order of `CN^(-)=(1)/(2)(8-2)=3`
