Which of the following elements does not form hydride by direct heating with dihydrogen?
(a) Be (b) Mg (c) Sr (d) Ba

Solution

The answer is (a). Be.

Except for Be, all alkaline earth metals form hydrides $(M H_{2})$ on directly heating with $H_{2} - B e H_{2}$ can't be prepared by the direct action of $H_{2}$ on Be. It is prepared by the action of $L i A / H_{4}$
$2 B e C l_{2} + L i A I H_{4} ⟶ 2 B e H_{2} + L i C l + A i C l_{3}$
