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

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

Text Solution

Verified by Experts

The correct Answer is:
C
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`
