Section-D: Comprehension Type
White crystalline solid (A) reacts with H2 to form a highly associated liquid (B) and a monoatomic, colorless 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 to produce (A).
Which of the following is correct for the white crystalline solid (A)?
