Q. The reaction of $C{l}_2$ gas with cold dilute and hot concentrated NaOH in water give sodium salt of two (different) oxoacids of chlorine P and Q respectively. The $C{l}_2$ gas reacts with $S{O}_2$ gas, in presence of charcoal to give a product R. R reacts with white phosphorous to give a compound S. On hydrolysis, S gives an oxoacid of phosphorous T.
R, S and T, respectively are:

1. $S{O}_{2}C{l}_2,PC{l}_5$ and $H_{3}P{O}_4$
2. $S{O}_{2}C{l}_2,PC{l}_3$ and $H_{3}P{O}_3$
3. $SOC{l}_2,PC{l}_3$ and $H_{3}P{O}_2$
4. $S{O}_{2}C{l}_2,PC{l}_5$ and $H_{3}P{O}_4$

Q.

1. True

2. False

Q.
