Question

What happens if the factors in column A are increased?

$\begin{array}{cc}A& B\\ \text{A) Cation size}& I)\text{Polarizability increases}\\ \text{B) Cation charge}& \text{II) Polarizing power decrease}\\ \text{C) Anion Charge}& \text{III) Polarizability increases}\\ \text{D) Anion Size}& \text{IV) Polarizing power increases}\end{array}$

• A. A - II, B - IV, C - I, D - III
• B. A - I, B - IV, C - II, D - III
• C. A - II, B - III, C - I, D - IV
• D. A - I, B - III, C - II, D - IV

Answer 1

The correct option is A

A - II, B - IV, C - I, D - III

Smaller the cation and more its charge, more is its power to distort the electron cloud of anion. Thus,

$cationsize\propto \frac{1}{polarizingpower}$

$Cationcharge\propto polarizingpower$

Larger the size of anion and its charge, more is its polarizability.

Thus,

$Anionsize\propto polarizability$

$Anioncharge\propto polarizability$
