(A) Ionic hydride
(e) Covalent hydride
(C) Metallic hydride
(D) Polymeric hydride​

Answer 1

Answer:

polymeric hydride

Explanation:

polymeric hydride

Answer 2

CrH is an example of metallic hydride.

• Chromium hydride or CrH is formed by a 3d block transition metal Cr and H.
• It is colourless. CrH exists as a close pack solid structure.
• It is a metallic hydride. It is a highly reactive metallic hydride.
• CrH is highly paramagnetic and has a high dipole moment and it is polar.
• Hence the correct option is C.
