Question

Reaction of $BeO$ with ammonia and hydrogen fluoride gives A which on thermal decomposition gives $BeF _2$ and $NH _4 F$ What is ' $A ^{\prime}$ ?

A

$\left( NH _4\right) BeF _3$

B

$H _3 NBeF _3$

C

$\left( NH _4\right) Be _2 F _5$

D

$\left( NH _4\right)_2 BeF _4$

Answer

$\left( NH _4\right)_2 BeF _4$

Explanation

Solution

BeO+2NH3+4HF→(NH4)2BeF4+H2O
(NH4)2BeF4⟶ΔBeF2+NH4F
