Elements of which of the following group(s) of periodic table do not form hybrides?
Elements of which of the following group(s) of periodic table do not form hybrides?
Groups 7, 8, 9
Group 13
Group 15, 16, 17
Group 14
Solution
The region of the periodic table from group 7 to 9 is referred to as the hydride gap as they do not form hydrides. Examples of such elements are \(\mathrm{Mn}, \mathrm{Fe}, \mathrm{Co}, \mathrm{Ru}\) etc. These elements do not form hydrides on account of low affinity for hydrogen in their normal oxidation states. Hence, the correct option is (a).
