Among `CaH_2,NaH, NH_3`, and `B_2 H_6` which are covalent hydrides?

A

`NH_3 and B_2 H_6`

B

`NaH, and CaH_2`

C

`NaH, and NH_3`

D

`CaH_2 and B_2H_6`

Text Solution

Verified by Experts

The correct Answer is:
A
N and B belong top-block and since the electronegativity difference between these elements and H is very less, they form covalent hydrides.
