(a) SF_6is not easily hydrolysed. Explain. (b) Ozone is used for purifying air in crowded places such as cinema halls, tunnels, etc. Explain. (c) Why oxide ion is called hard ion ? Explain. |

Answer» Solution :(a)` SF_6`is chemically inert and THEREFORE, does not GET hydrolysed. Its inert nature is due to the presence of stearically protected sulphur atom which does not allow thermodynamically favourable HYDROLYSIS reaction. (B) Ozone is an endothermic compound and easily decomposes to produce `O_2`as: ` 2O_3 to 3O_2` Therefore, it purifies crowded places. (c) Oxide ION is very small in size and therefore, it cannot be easily polarized. Hence, it is called hard ion. |
