`BeCl_(2).4H_(2)Ooverset(Delta)to "P"`
The product P is

A

`BeCl_(2)`

B

BeO

C

`Be(OH)_(2)`

D

BeOCI

Text Solution

Verified by Experts

The correct Answer is:
C
Anhydrous beryllium halides cannot be obtained from materials made in aqueous solution because the hydrated ion `[Be(H_(2)O)_(4)]^(2+)` is formed e.g., `[Be(H_(2)O)_(4)]Cl_(2)` or `[Be(H_(2)O)_(4)]F_(2)`. Attempts to dehydrate result in hydrolysis:
`[Be(H_(2)O)_(4)]Cl_(2)overset(Delta)toBe(OH)_(2)+2HCl`
