Which of the following complex is optically inactive?
Options A [ R h C l ( C O ) ( P P h 3 ) ( N H 3 ) ] \left[\mathrm{RhCl}(\mathrm{CO})\left(\mathrm{PPh}_3\right)\left(\mathrm{NH}_3\right)\right] [ RhCl ( CO ) ( PPh 3 ) ( NH 3 ) ] B \left[\mathrm{Fe}\left(\mathrm{C}_2 \mathrm{O}_4\right)_3\right]^{3-} C [ F e ( e n ) 2 C l 2 ] \left[\mathrm{Fe}(e n)_2 \mathrm{Cl}_2\right] [ Fe ( e n ) 2 Cl 2 ] D [ Pd ( e n ) 2 C l 2 ] \left[\operatorname{Pd}(e n)_2 \mathrm{Cl}_2\right] [ Pd ( e n ) 2 Cl 2 ] Correct answer A. [ R h C l ( C O ) ( P P h 3 ) ( N H 3 ) ] \left[\mathrm{RhCl}(\mathrm{CO})\left(\mathrm{PPh}_3\right)\left(\mathrm{NH}_3\right)\right] [ RhCl ( CO ) ( PPh 3 ) ( NH 3 ) ]
Step-by-step solution
\left[\operatorname{RhCl}(\mathrm{CO}) \left(\mathrm{PPh}_3\right)\left(\mathrm{NH}_3\right)\right] is optically inactive as it is square planar complex. It has plane of symmetry.
