Question

Select the correct statement for the sulphuric acid.

(I) It has high boiling point and viscosity.

(II) There are two types of bond lengths in its bivalent anion.

(III) pp-dp bonding between sulphur and oxygen is observed.

(IV) Sulphur has the same hybridisation that is of boron in diborane.

• A. II and III only
• B. II, III and IV only
• C. I, III and IV only
• D. III and IV only

Answer 1

Answer: (C)

I, III and IV only

Answer 2

(I)

As a result of H-bonding, number of sulphuric acid molecules are associated to form cluster. Hence it has high boiling point and viscosity.

(II) All S — O bond lengths are equal due to resonance.

(III)

(IV)
