Among `CaH_2, BeH_2 , BaH_2`, the order of ionic character is

A

`BeH_(2) lt BaH_(2) lt CaH_(2)`

B

`CaH_(2) lt BeH_(2) lt BaH_(2)`

C

`BeH_(2) lt CaH_(2) lt BaH_(2)`

D

`BaH_(2) lt BeH_(2) lt CaH_(2)`

Text Solution

Verified by Experts

The correct Answer is:
C
For `2^(nd)` group hydribes on moving doen the group metallic character of metals increases so ionic character of metal hydribe increases.
Hence the option (3) should be correct answer.
