Q16 / 90 · JEE Main 2009 · Chemistry

Which of the following has an optical isomer ?

  • A
    $\left[\mathrm{CO}\left(\mathrm{NH}_3\right)_3 \mathrm{Cl}\right]^{+}$
  • B
    $\left[\mathrm{CO}(\text { en })\left(\mathrm{NH}_3\right)_2\right]^{2+}$
  • C
    $\left[\mathrm{CO}\left(\mathrm{H}_2 \mathrm{O}\right)_4(\mathrm{en})\right]^{3+}$
  • Correct answer
    D
    $\left[\mathrm{CO}(\mathrm{en})_2\left(\mathrm{NH}_3\right)_2\right]^{3+}$

Solution

It is an octahedral complex of the type $\left[\mathrm{M}(\mathrm{AA})_2 \mathrm{X}_2\right]$ Where AA is bidentate ligand.

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