AP EAMCET · Chemistry · d and f Block Elements
In long form of periodic table, the \(d\)-block element which forms interstitial hydride is
- A Mo
- B W
- C \(\mathrm{Ni}\)
- D \(\mathrm{Cr}\)
Answer & Solution
Correct Answer
(D) \(\mathrm{Cr}\)
Step-by-step Solution
Detailed explanation
Generally, group 6, 7, 8 and 9 has low affinity towards hydrogen when they are in their normal oxidation states. This prevents the formation of metal hydrides. But chromium \((\mathrm{Cr})\) is an exception. The \(\mathrm{Cr}\) absorb hydrogen in almost \(1: 1\) stoichiometric…
