(a)-(iv), (b)-(v), (c)-(ii), (d)-(iii)
(a)-(v), (b)-(iv), (c)-(ii), (d)-(iii)
Correct Option:
Solution:
(a) Hypophosphorus acid : $\mathrm{H}_{3} \mathrm{PO}_{2}$
$(+1) 3+x+(-2) 2=0$
$x=+1$
(b) Orthophosphoric acid: $\mathrm{H}_{3} \mathrm{PO}_{4}$
$(+1) 3+x+(-2) 4=0$
$x=+5$
(c) Hypophosphoric acid: $\mathrm{H}_{4} \mathrm{P}_{2} \mathrm{O}_{6}$
$(+1) 4+2 x+(-2) 6=0$
$x=+4$
(d) Orthophosphorous acid: $\mathrm{H}_{3} \mathrm{PO}_{3}$
$(+1) 3+x+(-2) 3=0$
$x=+3$
