Among CaH₂, BeH₂, BaH₂, the order of ionic character is (NEET 2018) (a) CaH BeH BaH (b) BeH BaH CaH (c) BeH CaH BaH (d) BaH BeH CaH

Ionic character of a metal increases down the group and it decreases from left to right in the periods. Group I and group II elements form ionic bonds vigorously due to high ionic character. The same principle follows for metal hydrides, metal halides, and metal oxides. And the order follows as. Therefore, option c is correct.
