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

Question

1. It forms Be₂C . 2. Its salts rarely hydrolyze. 3. Its hydride is electron-deficient and polymeric. 4. It is rendered passive by nitric acid.

Doubtly AI · Accepted Answer

Answer: 2. Its salts rarely hydrolyze. Key idea: Be is small and highly polarising, so its salts hydrolyse readily. Be forms Be₂C (carbide): correct. BeH₂ is electron-deficient and polymeric: correct. Be is passivated by conc. HNO₃ : correct. Be salts do hydrolyse easily (e.g. [Be(H₂O)₄]²⁺ is acidic), so "rarely hydrolyse" is incorrect.
