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

Options

A. It is rendered passive by nitric acid
B. its forms `Be_2C`
C. Its salts rarely hydrolyse
D. Its hydride is electron-deficient and polymeric

Answer

C

Explanation

Beryllium salts are covalent in nature because of very small size of `Be^(2+)` ion and its high polarising power, so it is easily hydrolysed.
e.g.`BeCl_2+2H_2O to Be(OH)_2+2HCl`
