A certain hypohalite on treating with hot and conc. NaOH forms anions P and Q. More stable anion among P and Q can be obtained by neutralizing Its conjugate acid X. Upon heating X to very high temperature, a compound Y Is formed, which is used in estimation of a toxic gas which have 300 times stronger affinity for haemoglobin than dioxygen Then which of the following statements are true.
A. (A) X Is Hl
B. (B) Y is `Cl_2O_5`
C. (C) Final product Y, has total no. of bonds 5.
D. (D) Y on reacting with toxic gas produces a gas which Is used in fire extinguisher.
