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). According to Molecular Orbital Theory, which of the following is correct about the molecule (D) ?A. its bond order is 2.0B. it has two unpaired electrons in `pi`-bonding M.O.C. both the above are correctD. none of these is correct
