Identify the pair of hydrides which have polymeric structure:
Show Hint
- LiH, NaH
- BeH\(_2\), MgH\(_2\)
- NH\(_3\), CH\(_4\)
B\(_2\)H\(_6\), H\(_2\)O
The Correct Option is B
Solution and Explanation
Both BeH\(_2\) and MgH\(_2\) are known to form polymeric structures. BeH\(_2\) can adopt a linear polymeric structure due to bridging hydrogen atoms, while MgH\(_2\) forms polymeric networks in its crystal lattice.
