Q14 / 180 · COMEDK 2014 · Chemistry

The non-existence of $\mathrm{PbI}_{4}$ and $\mathrm{PbBr}_{4}$ is due to

  • A
    highly oxidising nature of $\mathrm{Pb}^{4+}$ ions
  • B
    highly reducing nature of $I^{-}$and $\mathrm{Br}^{-\infty}$ ions
  • C
    larger size of $\mathrm{Pb}^{4+}, \mathrm{Br}^{-}$and $\mathrm{I}^{-}$ions
  • Correct answer
    D
    Both (a) and (b)

Solution

The non-existence of $\mathrm{PbI}_{4}$ and $\mathrm{PbBr}_{4}$ is probably due to the strong oxidising power of $\mathrm{Pb}^{4+}$ ions and strong reducing power of $\mathrm{I}$ and $\mathrm{Br}^{-}$ions.

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