In Spectrochemical series , chorine is above than water . I .e ` Cl gt 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

none of the above

Text Solution

Verified by Experts

The correct Answer is:
B

When ligands are arranged in ascending order of crystal field splitting energy , `Delta _(0) ` they produce a spectrochemical series .
in comparison to `H_(2) O,` is strong `rho ` - donor and good `pi`- acceptor , therefore it is a strong ligand then `H_(2)O` hence , in the spectrochemical series Cl is above than water.
