Vedclass · Answer

(A) Beryllium $(Be)$ is an alkaline earth metal,but it shows anomalous behavior compared to other members of the group.$Be$ does not react directly with $H_2$ to form $BeH_2$ because of its high ionization energy and small size.$BeH_2$ is typically prepared by the reaction of $BeCl_2$ with $LiAlH_4$.Therefore,the reaction $Be + H_2 \longrightarrow BeH_2$ is incorrect.
