A crystalline solid (A) reacts with hydrogen gas to form a monoatomic gas (B) and a highly associated liquid ( C).(A) is soluble in water and undergoes hydroloysis slowly to form (B),(C ) and a diatomic gas (D).When pure and dry (D) is subjected to a silent electric discharge an another pale blue gas (E) is produced which like (A) also acts a strong oxidising agent.(E) dissolves in potassium hydroxide forming an orange coloured solid which is paramagnetic in nature. (A) reacts with `IF_5, SbF_5, PF_5` etc to form the addition compounds. (C ) forms an addition compound (F) with KF with when electrolysed in molten state forms a most reactive gas (G).(B) and (G) (taken in 2:1) ratio when heated in nickel tube at `400^@ C` and 6 atm pressure forms (A).The first ionization energy `(IE_1)` of (B) is fairly close to (D).
Which of the following statements is correct for (A) ?

Options

A. The central atom of (A) is `sp^3d` hybridised with three lone pairs of electrons
B. (A) reacts with `S_8` molecules in presence of (C ) to form a compound in which the S atom is `sp^3d^2` hybridised
C. (A) reacts with `SbF_5` as a lewis base
D. All of these

Answer

D

Explanation

(A)
(B)`S_8+24XeF_2to24Xe+8SF_6(Stosp^3d^2)`
(C )`XeF_2+SbF_5 to [XeF]^(+)[SbF_6]^(-)`
