In context with beryllium, which one of the following statements is incorrect ?
A.
It is rendered passive by nitric acid
B.
It forms $$B{e_2}C$$
C.
Its salts rarely hydrolyse
D.
Its hydride is electron-deficient and polymeric
Answer :
Its salts rarely hydrolyse
Solution :
Beryllium salts are covalent in nature because of very small size of $$B{e^{2 + }}\,ion$$ and its high polarising power, so it is easily hydrolysed.
e.g. $$BeC{l_2} + 2{H_2}O \to Be{\left( {OH} \right)_2} + 2HCl$$
