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

The correct option is A Its salts rarely hydrolyze.

(BeH₂)_n beryllium hydride, it is electron deficient and polymer of BeH₂.

Be, Al, Cr are having passive nature with HNO₃

Beryllium salts (BeCl₂) easily hydrolyse.
