The correct orderof bond order values among the following : A . NO^(-)

1.	The correct orderof bond order values among the following : A . NO^(-) B.NO^(+) C.NOD.NO^(2+) E. NO^(2-) is
Answer» `A lt D lt C lt B lt E` `D = B lt A lt E LE C ` `E lt A lt D = C lt B` `B lt C lt D lt A lt E ` SOLUTION : `NO=KK sigma_(2)^(2) sigma_(2s)^(2) sigma_(2p_(Z))^(2) pi_(2p_(x))^(2)pi_(2p_(y))^(2)pi_(2p_(x))^(1)` B.O. `= (1)/(2) (8-3) = (5)/(2) = 2.5 ` `NO^(-)=KK sigma_(2)^(2) sigma_(2s)^(2) sigma_(2p_(z))^(2) pi_(2p_(x))^(2)pi_(2p_(y))^(2)pi_(2p_(x))^(1)pi_(2p_(y))^(1)` B.O. = `(1)/(2) (8-4)= 2` `NO^(2-)=KK sigma_(2)^(2) sigma_(2s)^(2) sigma_(2p_(z))^(2) pi_(2p_(x))^(2)pi_(2p_(y))^(2)pi_(2p_(x))^(2)pi_(2p_(y))^(1)` B.O. = `(1)/(2) (8-5) = (3)/(2) = 1.5 ` `NO^(+)=KK sigma_(2)^(2) sigma_(2s)^(2) sigma_(2p_(z))^(2) pi_(2p_(x))^(2)pi_(2p_(x))^(2)pi_(2p_(y))^(2)` B.O. `= (1)/(2) (8-2) = 3 ` `NO^(2+)=KK sigma_(2)^(2) sigma_(2s)^(2) sigma_(2p_(z))^(2) pi_(2p_(x))^(2)pi_(2p_(y))^(1)` B.O. ` = (1)/(2) (7-2) = (5)/(2) = 2.5 ` THUS `NO^(2-) lt NO^(-) NO = NO^(2-) lt NO^(+)`, i.e. `E lt A lt C = D lt B `
