The molar conductivity of 0.007M acetic acid is 20 S² mol⁻¹. What is the dissociation constant of acetic acid? Choose the correct option.
[Λ°(H⁺) = 350 Scm² mol⁻¹]
[Λ°(CH₃COO⁻) = 50 Scm² mol⁻¹]

HClO₄ is the most acidic compound.

Group number = 11 (Atomic number = 111)

Heavier element of p block do not from pπ− pπ bonds as their atomic orbital are so large and diffius that they cannot have effecitve overlapping.

The inertness of ? subshell electrons towards bond formation is known as inert pair effect. This effect increases down the group thus, for Sn,  oxidation state is more stable, whereas, for Pb,  oxidation state is more stable, i.e.,  is reducing while  is oxidising.
