Which of the following statements regarding $\mathrm{Hg}^{2+}$ (ionic radius $116 \mathrm{pm}$ ) and $\mathrm{Ca}^{2+}$ (ionic radius $114 \mathrm{pm}$ ) is correct?
  1. $\mathrm{Hg}^{2+}$ ion has more polarizing effect on an anion as compared to $\mathrm{Ca}^{2+}$ ion
  2. $\mathrm{Hg}^{2+}$ ion has less polarizing effect on an anion as compared to $\mathrm{Ca}^{2+}$ ion
  3. Both $\mathrm{Hg}^{2+}$ ion and $\mathrm{Ca}^{2+}$ have equal polarizing effect on an anion
  4. Both $\mathrm{Hg}^{2+}$ ion and $\mathrm{Ca}^{2+}$ have no polarizing effect on an anion

Solution

$\mathrm{Hg}^{2+}$ ion belongs to transition metal and $\mathrm{Ca}^{2+}$ ion to alkaline-earth metal. Thus $\mathrm{Hg}^{2+}$ ion has more polarizing effect on an anion.
