Q55 / 180 · NEET 2016 (Phase 2) · Chemistry

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

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

Solution

Salts of beryllium are readily hydrolyzed due to the presence of vacant

p

-orbital. So, given option is incorrect statement. All other statements are correct. It is rendered passive by nitric acid. It forms beryllium carbide. And its hydride is electron deficient with formula BeH₂.

Hence, the correct answer is option: 'C'.
