Which of the following complex will have tetrahedral the given ligands is
A
NH3<Cl−<CN−<F−<CO<H2O
B
F−<Cl−<NH3<CN−<H2O<CO
C
Cl−<F−<H2O<NH3<CN−<CO
D
CO<CN−<NH3<H2O<F−<Cl−
Answer
Cl−<F−<H2O<NH3<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}$$
