The covalent character of the following chlorides follow the order

  • A
    \(\mathrm{HgCl}_2 < \mathrm{CdCl}_2 < \mathrm{ZnCl}_2\)
  • Correct answer
    B
    \(\mathrm{ZnCl}_2 < \mathrm{CdCl}_2 < \mathrm{HgCl}_2\)
  • C
    \(\mathrm{CdCl}_2 < \mathrm{ZnCl}_2 < \mathrm{HgCl}_2\)
  • D
    \(\mathrm{HgCl}_2 < \mathrm{ZnCl}_2 < \mathrm{CdCl}_2^2\)

Solution

\(\mathrm{ZnCl}_2\) and \(\mathrm{CdCl}_2\) are ionic, but \(\mathrm{HgCl}_2\) is covalent.

Hence, the correct answer is option: 'B'.
