Which of the following is correct with respect to bond length of the s

1.	Which of the following is correct with respect to bond length of the species ?
Answer» `C_(2) gt C_(2)^(2-)` `B_(2)^(+) gt B_(2)` `Li_(2)^(+) gt Li_(2)` `O_(2) gt O_(2)^(-)` SOLUTION :Bond order : `C_(2)= 2 , C_(2)^(2-) = 3 , B_(2) = 1 , B_(2)^(+) = 0.5 ` , `Li_(2) = 1 , Li_(2)^(+) = 0.5 , N_(2)= 3 , N_(2)^(+) = 2.5 , O_(2) = 2 ` `O_(2)^(-) = 1.5` . Greater the bond order , SHORTER is the bond length
