(A) : Viscosity of H2SO4 > viscosity of HCl(R) : Molecules of H2SO4 are involved in H-bonding but not the molecules of HCl

Statement (A) is true because H2SO4 has a higher viscosity than HCl at the same temperature and pressure. Viscosity is the measure of a fluid's resistance to flow, and it is determined by the intermolecular forces between the molecules of the fluid. The stronger the intermolecular forces, the higher the viscosity.Statement (R) is also true because H2SO4 can form intermolecular hydrogen bonds due to the presence of polar O-H and S=O bonds in its molecule, whereas HCl is a non-polar molecule and does not have the ability to form hydrogen bonds. Hydrogen bonds are stronger than other intermolecular forces such as London dispersion forces, which are present in both H2SO4 and HCl. Therefore, the presence of hydrogen bonding in H2SO4 increases its intermolecular forces and makes it more viscous than HCl.So, both (A) and (R) are correct and (R) is the correct explanation of (A).

Detailed Solution

Statement (A) is true because H₂SO₄ has a higher viscosity than HCl at the same temperature and pressure.
Viscosity is the measure of a fluid's resistance to flow, and it is determined by the intermolecular forces between the molecules of the fluid.
The stronger the intermolecular forces, the higher the viscosity.
Statement (R) is also true because H₂SO₄ can form intermolecular hydrogen bonds due to the presence of polar O-H and S=O bonds in its molecule, whereas HCl is a non-polar molecule and does not have the ability to form hydrogen bonds.
Hydrogen bonds are stronger than other intermolecular forces such as London dispersion forces, which are present in both H₂SO₄ and HCl.
Therefore, the presence of hydrogen bonding in H₂SO₄ increases its intermolecular forces and makes it more viscous than HCl.
So, both (A) and (R) are correct and (R) is the correct explanation of (A).
