Question

For which of the following diatomic molecules does the bondorder increase with the loss of two electons, forming thecorresponding cation with a 2+ charge? ___ a. B2 --> B22+ +2e- ___ b. C2 ---> C22++ 2e- ___ c. N2 --> N22+ +2e- ___ d. O2 --> O22+ +2e- For which of the following diatomic molecules does the bondorder increase with the loss of two electons, forming thecorresponding cation with a 2+ charge? ___ a. B2 --> B22+ +2e- ___ b. C2 ---> C22++ 2e- ___ c. N2 --> N22+ +2e- ___ d. O2 --> O22+ +2e- ___ d. O2 --> O22+ +2e-

Explanation / Answer

The no . of electrons involved in B2 is = 5 + 5 = 10 Bond order is = { No . of electrons in bonding orbital - No .of electrons in anti bonding orbital } / 2 The table containing no . of electrons & the correspondingBond order is given below        No . ofelectrons      Bond order -----------------------------------------------       1                                 1/2       2                                   1       3                                 1/2        4                                   0       5                                    1/2       6                                   1       7                                   1/2       8                                     0       9                                    1/2       10                                  1        11                                  1.5        12                                   2.0       13                                  2.5        14                                   3.0       15                                    2.5        16                                   2.0        17                                   1.5        18                                   1.0         19                                    0.5         20                                    0 The no . of electrons involved in B2 is = 5 + 5 = 10 ,so bondorder is 1 The no . of electrons involved in B2 2+ is = 5 + 5 -2= 8 ,so bond order is 0           1          0 ___ a. B2 --> B22+ +2e-            2             1            2             1 ___ b. C2 ---> C22++ 2e-            3          2            3          2 ___ c. N2 --> N22+ +2e-            2          3 ___ d. O2 --> O22+ +2e So , in the case (d) only the bond order increases
