The reactions of Cl2 gas with cold-dilute and hot-concentrated NaOH in water give sodium salts of two (different) oxoacids of chlorine, P and Q, respectively. The Cl2 gas reacts with SO2 gas, in presence of charcoal, to give a product R. R reacts with white phosphorus to give a compound S. On hydrolysis, S gives an oxoacid of phosphorus, T.1. P and Q, respectively, are the sodium salts of(A) hypochlorus and chloric acids(B) hypochlorus and chlorus acids(C) chloric and perchloric acids(D) chloric and hypochlorus acids2. R, S and T, respectively, are(A) SO2Cl2, PCl5 and H3PO4(B) SO2Cl2, PCl3 and H3PO3(C) SOCl2, PCl3 and H3PO2(D) SOCl2, PCl5 and H3PO4
