<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> NEET 2019

1. $PC{l}_5$ molecule is non-reactive
2. Axial $P-Cl$ bonds are longer than equatorial $P-Cl$ bonds
3. Two axial $P-Cl$ bonds make an angle of $180°$ with each other
4. Three equatorial $P-Cl$ bonds make an angle of $120°$ with each other

Q. Which of the following statement(s) is/are correct for $PC{l}_5$?

1. $P$ atom is $s{p}^{3}d$ - hybridized and has trigonal bipyramidal geometry
2. It acts as a Lewis acid
3. On hydrolysis it forms phosphoric acid
4. Axial $Cl$ atoms are closer to equatorial $Cl$ atoms

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