MCQ
Which of the following complex is optically inactive
  • ✓
    $\left[ RhCl ( CO )\left( PPh _{3}\right)\left( NH _{3}\right)\right]$
  • B
    $\left[ Fe \left( C _{2} O _{4}\right)_{3}\right]^{3-}$
  • C
    $\left[ Fe ( en )_{2} Cl _{2}\right]$
  • D
    $\left[ Pd ( en )_{2} Cl _{2}\right]$
✓

Answer

Correct option: A.
$\left[ RhCl ( CO )\left( PPh _{3}\right)\left( NH _{3}\right)\right]$
a
The coordination complex $\left[ RhCl ( CO )\left( PPh _{3}\right)\left( NH _{3}\right)\right]$ is a square planar complex. Hence, it is optically inactive.
