Question

Which one of the following compounds is not a protonic acid ? (A) SO2(OH)2 (B) B(OH)3 (C) PO(OH)3 (D) SO(OH)2

Tardigrade Admin · Accepted Answer

B(OH)3 in water gives H+ ions as follows B(OH)3+H2O leftharpoons [B(OH)-4]+H+ Thus, it is not a protonic acid i.e., it does not give its hydrogen H+ ions

Q. Which one of the following compounds is not a protonic acid ?

$S O_{2} (O H)_{2}$

$B (O H)_{3}$

$PO (O H)_{3}$

$SO (O H)_{2}$

$B (O H)_{3}$ in water gives $H^{+}$ ions as follows
$B (O H)_{3} + H_{2} O ⇌ [B (O H)_{4}^{-}] + H^{+}$
Thus, it is not a protonic acid i.e., it does not give its hydrogen $H^{+}$ ions

SO2​(OH)2​

B(OH)3​

PO(OH)3​

SO(OH)2​

B(OH)3​ in water gives H+ ions as follows B(OH)3​+H2​O⇌[B(OH)4−​]+H+ Thus, it is not a protonic acid i.e., it does not give its hydrogen H+ ions

$S O_{2} (O H)_{2}$

$B (O H)_{3}$

$PO (O H)_{3}$

$SO (O H)_{2}$
