1.	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) ?
Answer» The central atom of (A) is `sp^3d` hybridised with three lone pairs of electrons (A) REACTS with `S_8` molecules in PRESENCE of (C ) to FORM a compound in which the Satom is `sp^3d^2` hybridised (A) reacts with `SbF_5` as a LEWIS base All of these Solution :(A) (B)`S_8+24XeF_2to24Xe+8SF_6(Stosp^3d^2)` (C )`XeF_2+SbF_5 to [XeF]^(+)[SbF_6]^(-)`
