Question

Which of the following statement is not applicable to $H_{2}S{O}_4$ ?

• A. The molecules are associated by H-bonds
• B. Oxidation state of S is +6
• C. The hybrid state of S and O atoms of OH groups is same
• D. The acid always exhibits a basicity of two

Answer 1

Answer: (D)

As $H_{2}S{O}_4$ forms two series of salts i.e, sulphates and bisulphates, hence, it can exhibit basicity of 1 and 2. It means it does not always show basicity 2. Rest other statements given here are correct as it has hydrogen bonds, +6 oxidation state of S-atom and also have $s{p}^3$ hybridisation for both sulphur and oxygen atoms.
