Which of the following is correct?A. The number of electrons present in the valence shell of `S` in `SF_6` is `12`.B. The rate of ionic reaction is very low.C. According to `VSEPR` theory, `SnCl_2` is a linear molecule.D. The correct order of stability to form ionic compounds among `Na^(+)`, `Mg^(2+)`, and `Al^(3+)` is `Al^(3+)gtMg^(2+)gtNa^(+)`. |

Answer» Correct Answer - A `S` in `SF_6` forms `6` covalent bonds and has no lone pair. Thus, it has 12 valence electrons. Ionic reactions are very fast. `SnCl_2` (`SN` is `2+1=3`) is angular. Stability order to form ionic compounds is `Al^(3+) ltMg^(2+)ltNa^(+)`. |
