Question

In context with beryllium, which one of the following statements is incorrect?

• A. Its salts rarely hydrolyze
• B. Its hydride is electron-deficient and polymeric
• C. It is rendered passive by nitric acid.
• D. It forms $B{e}_{2}C$

Answer 1

Answer: (A)

$\begin{array}{c}\text{(A) Be-Salts are highly covalent and hence are easily hydrolysed.}\\ \text{(B)}{\left(Be{H}_2\right)}_n\text{[Beryllium hydride] is electron deficient and}\\ \text{is in polymeric form.}\\ \text{(c) Beryllium is not soluble in dilute or cold nitric acid, but}\\ \text{is readily dissolved by hot concentrated nitric acid.}\\ \text{(D) Beryllium forms carbide,}B{e}_{2}C\text{.}\end{array}$

Option A is correct answer
