Q50 / 180 · AIIMS 2009 · Chemistry

Incorrect statement about Ge is

  • A
    $\mathrm{GeO}_2$ is weakly acidic
  • B
    $\mathrm{Ge}(\mathrm{OH})_2$ is amphoteric
  • Correct answer
    C
    $\mathrm{GeCl}_2$ is more stable than $\mathrm{GeCl}_4$
  • D
    $\mathrm{Ge}-\mathrm{Ge}$ bond energy is lesser than that of $\mathrm{Si}-\mathrm{Si}$.

Solution

$\mathrm{GeCl}_4$ is more stable than $\mathrm{GeCl}_2$. Ge has greater tendency to form +4 state than +2 state.

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