In which of the following hydrides, hydrogen exists in negative oxidation state?

A

`HCl`

B

`NaH`

C

`CaH_(2)`

D

`HI`

Text Solution

Verified by Experts

The correct Answer is:
B, C
`NaH` and `CaH_(2)` are ionic hydrides and `Na^(o+)` and `Ca^(2+)` lose electron which is gained by `H` to form `H^(ɵ)` ion.
