Vedclass · Answer

(D) According to the spectrochemical series,ligands are arranged in increasing order of their crystal field splitting energy $(CFSE)$. $CO$,$CN^-$,and $NO_2^-$ are all strong field ligands that cause large crystal field splitting. Among the given options,$CO$ is a very strong $\pi$-acid ligand,but $CN^-$ and $NO_2^-$ also exhibit significant splitting. In the context of standard chemistry problems,all these ligands are considered strong field ligands that produce high crystal field splitting compared to halides or water. Therefore,the correct answer is $D$.
