Which of the following elements does not form hydride by direct heating with dihydrogen?
A.
$$Be$$
B.
$$Mg$$
C.
$$Sr$$
D.
$$Ba$$
Answer :
$$Be$$
Solution :
All the elements except beryllium combine with hydrogen upon heating to form their hydrides, $$M{H_2}.$$
$$Be{H_2},$$ however, can be prepared by the reaction of $$BeC{l_2}$$ with $$LiAl{H_4}.$$
$$2BeC{l_2} + LiAl{H_4} \to $$ $$2Be{H_2} + LiCl + AlC{l_3}$$
