Question

Strong field ligands, such as $C{N}^{-}$ usually produce low spin complexes and large crystal field splitting.

If true enter 1, else enter 0.

Answer 1

The correct answer is 1.

Strong field ligands, such as $C{N}^{-}$, usually produce low spin complexes and large crystal field splitting.

The spectrochemical series is an empirically derived list of ligands ordered by the size of the splitting $\Delta$ that they produce. It can be seen that the low-field ligands are all $\pi$-donors (such as $I^{-}$), the high field ligands are π-acceptors (such as $C{N}^{-}$ and $CO$) and ligands such as $H_{2}O$ and $N{H}_3$, which are neither are in the middle.
