Q15 / 100 · BITSAT 2024 (Memory Based Paper 2) · Chemistry

The correct statement among the following is;

  • A
    Ferrocene has two cyclohexadiene rings coordinated to iron atom.
  • Correct answer
    B
    Ferrocene has two cyclopentadienyl anion rings bonded to iron (II) ion.
  • C
    Perxenate ion is $\left[\mathrm{XeO}_2 \mathrm{~F}_2\right]^{2-}$
  • D
    Perxenate ion is tetrahedral is shape.

Solution

Ferocene is $\mathrm{Fe}\left(\eta^5-\mathrm{C}_5 \mathrm{H}_5\right)_2$ Perxenate ion is $\left[\mathrm{XeO}_6\right]^4$ which is octahedral.

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