Question

Which of the following is an example of interstitial hydride? O MgH2 O BeH2 O LaH2.87 O CHA​

Answer 1

Answer:

LaH2.87 is an example of interstitial hydride.

Explanation:

Interstitial hydride is a metallic hydride that formed that hydrogen bonds with the transition metals. It is formed by the elements of group 3,4,5,10,11,12, d block. and f block elements. In these compounds, hydrogen occupies the interstitial sites in the metal lattice.

As La belongs to f block elements, so it will form the interstitial bond with hydrogen.

Hence, LaH2.87 is the only example of interstitial hydride.
