Question

The correct ascending order of ligand field strengths of the given ligands is

• A. $F^{-}<I^{-}<C{N}^{-}<H_{2}O<CO$
• B. $I^{-}<F^{-}<H_{2}O<CO<C{N}^{-}$
• C. $I^{-}<F^{-}<H_{2}O<C{N}^{-}<CO$
• D. $F^{-}<H_{2}O<I^{-}<C{N}^{-}<CO$
• E. $F^{-}<I^{-}<CO<H_{2}O<C{N}^{-}$

Answer 1

Answer: (C)

According to spectrochemical series, ligand field strength are

$I^{-}<F^{-}<H_{2}O<C{N}^{-}<CO$
