Q. In spectrochemical series chlorine is above than water i.e., $Cl\ >$ $H_{2}O$, this is due to
A) Good$\ \pi$-acceptor properties of Cl
B) Strong $\sigma -$donor and good$\ \pi$-acceptor properties of Cl
C) Good$\ \pi -$donor properties of Cl
D) Larger size of Cl than $H_{2}O$
Explanation
(b)
When ligands are arranged in ascending order of crystal field splitting energy, $\mathrm{\Delta}$, they produce a spectrochemical series.
In comparison to $H_{2}O,\ Cl$ is strong $\sigma$-donor and good $\pi$-acceptor, therefore it is a strong ligand than $H_{2}O$. Hence, in the spectrochemical series Cl is above than water.
