White crystalline solid (A) reacts with ...

White crystalline solid (A) reacts with `H_(2)` to form a highly associated liquid (B) and a monoatomic, colourless gas ( C).The liquid (B) is used for etching glass.Compound (A) undergoes hydrolysis slowly to form ( C).(B) and a diatomic gas (D) whose IE is almost similar to that of ( C).(B) forms an addition compound with KF to form (E).which is electrolysed in the molten state to form a most reactive gas (F) which combines with ( C) in 2:1 ratio of produce (A).
Which of the following is correct for the white crystalline solid (A) ?

A

It oxidises F to `F_2`

B

It on hydrolysis with alkali under goes disproportionation

C

It is obtained by the reaction of (C ) with `O_2F_2` at `118^@C`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
C
Compound (A) is `XeF_2` , so , `Xe+O_2F_2 overset(118^@C)to XeF_2 +O_2`
