Elements of which of the following group(s) of periodic table do not form hybrides?
Options
- AGroups 7, 8, 9
- BGroup 13
- CGroup 15, 16, 17
- DGroup 14
Correct answer
A. Groups 7, 8, 9
Step-by-step 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 ( Mn , Fe , Co , 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).
