Fill in the blanks by chossing the appropriate word/words from those given in the brackets: (increases, ionic radius, `CH_(2)`, same, sigma, ionic, 14, 2, decreases, 16, `CH_(3)`, pi, covalent, ionic)
When `N_(2)` goes to `N_(2)^(+)`, the N-N bond distance _____ and when `O_(2)` goes to `O_(2)^(+)` the O-O bond distance _______

Explanation

Increases, decreases
Bond order in `N_(2)` is 3 while same in `N_(2)^(+)` is 2.5, hence bond distance increases as `N_(2)` goes to `N_(2)^(+)`.
Bond order in `O_(2)` is 2 while same in `O_(2)^(+)` is 2.5, hence bond distance decreases as `O_(2)` goes to.
