Which of the following complex will have tetrahedral the given ligands is

A

NH3<Cl<CN<F<CO<H2ONH_{3} < Cl^{-} < CN^{-} < F^{-} < CO < H_{2}O

B

F<Cl<NH3<CN<H2O<COF^{-} < Cl^{-} < NH_{3} < CN^{-} < H_{2}O < CO

C

Cl<F<H2O<NH3<CN<COCl^{-} < F^{-} < H_{2}O < NH_{3} < CN^{-} < CO

D

CO<CN<NH3<H2O<F<ClCO < CN^{-} < NH_{3} < H_{2}O < F^{-} < Cl^{-}

Answer

Cl<F<H2O<NH3<CN<COCl^{-} < F^{-} < H_{2}O < NH_{3} < CN^{-} < CO

Explanation

Solution

In general, the ligands can be arranged in a series in the order in increasing field strength as

}{< NCS^{-} < EDTA^{4 -} < NH_{3} < en < NO_{2}^{-} < CN^{-} < CO}$$
