• B. $(A) \to (ii)$, $(B) \to (iv)$, $(C) \to (iii)$, $(D) \to (i)$
• C. $(A) \to (iii)$, $(B) \to (ii)$, $(C) \to (iv)$, $(D) \to (i)$
• D. $(A) \to (iv)$, $(B) \to (i)$, $(C) \to (ii)$, $(D) \to (iii)$

Answer 1

Answer: (C)

$(A) \to (iii)$, $(B) \to (ii)$, $(C) \to (iv)$, $(D) \to (i)$

Answer 2

$H _{3} P O _{2} \longrightarrow 3+ x -4=0$ $x =+1$ $H _{3} P _{3} O _{9} \longrightarrow 3+3 x -18=0$ $\Rightarrow 3 x =15$ $\Rightarrow x =+5$ $H _{3} P O _{4} \longrightarrow 3+ x -8=0$ $\Rightarrow x =+5$ $H _{3} P O _{3} \longrightarrow 3+ x -6=0$ $\Rightarrow x =+3$ (A) $H _{3} P O _{2} \longrightarrow$ monobasic acid having 1 removable $H ^{+}$ion. (B) $H _{3} P _{3} O _{9} \longrightarrow$ cyclic oxoacid (Refer to Image) (C) $H _{3} P O _{4} \longrightarrow$ Tribasic $\longrightarrow$ having $3$ removable $H ^{+}$ion.
