1.	Consider the statements : I . Bond length in N_(2)^(+) is 0.002 Å greater than in N_(2) II. Bond length in NO^(+) is 0.09 Å less than in NO III. O_(2)^(2-) hasshorter bond length than O_(2) which of the following statements are ture ?
Answer» I and II II and III I, II and III I and III Solution :Bond order of `N_(2)` is 3 and that of `N_(2)^(+)` is 2.5 . Greater the bond order , shorter is the bond length HENCE order of NO is 2.5 and that of `NO^(+)` is 3 THUS , bond length of `NO^(+)` is shorter . Hence ,II is TRUE Bond order of `O_(2)`is 2 while that ` O_(2)^(2-)` is 1. Thus, bond length of `O_(2)` is shorter . Hence , III is not ture .
