1.	Among CaH_(2),BeH_(2),BaH_(2), the order of ionic character is-
Answer» `BeH_(2) lt CaH_(2) lt BaH_(2)` `CaH_(2) lt BeH_(2) lt BaH_(2)` `BeH_(2) lt HaH_(2) lt CaH_(2)` `BaH_(2) lt BeH_(2) lt CaH_(2)`. SOLUTION :Down a group METALLIC character INCREASES. Thus IONIC character of the metal hydride increases down the group. Hence least ionic compound is `BeH_(2)`.
