From the data given in the following table,
| Ion | NO3- | SO42- | F- | I- |
|---|---|---|---|---|
| Ionic mobility (× 10-8 m2 S-1 V-1) | 19.8 | 8.5 | 5.9 | 4.4 |
the correct order for an effective radius of the anions in water at 25°C is
1
NO3- < SO42- < F- < I-
2
SO42- < NO3- < F- < I-
3
I- < F- < SO42- < NO3-
4
F- < SO42- < NO3- < I-
