Chemistry Question on p -Block Elements

Which one of the following compounds is not a protonic acid:

A

B(OH)3B(OH)_3

B

PO(OH)3PO(OH)_3

C

SO(OH)2SO(OH)_2

D

SO2(OH)2SO_2(OH)_2

Answer

B(OH)3B(OH)_3

Explanation

Solution

Protonic acids are substances that can donate a proton (H+ ion) in aqueous solution. Let's analyze the given compounds:
(A) B(OH) 3: Boron does not readily donate protons in aqueous solution, so this is not a protonic acid.
(B)PO(OH) 3: Phosphorous acid (H3PO3) is a protonic acid, as it can donate protons in aqueous solution.
(C) **SO(OH) 2: **Sulfurous acid (H2SO3) is a protonic acid, as it can donate protons in aqueous solution.
(D) **SO 2(OH)2: **This compound, sulfuric acid (H2SO4), is a well-known strong protonic acid.

So, among the given options, (A): B(OH)3 is not a protonic acid.
