As we discused

Spectrochemical series -

I^{-} < Br^{-}< SCN^{-}< Cl^{-}< S^{2^{-}}< F^{-}< OH^{-}< C_{2}O_{4}^{2-}< H_{2}O< EDTA< NH_{3}< en< Cn^{-}< CO

-

 

 On increasing strength of ligand wavelength of absorbed radiation decreases

order of spectrochemical series=H_{2}O< NH_{3}< e_{n}

Order of absorbed wavelength==e_{n}< NH_{3}< H_{2}O


Option 1)

[Co(en)3]3+, [Co(NH3)6]3+, [Co(H2O)6]3+

This is correct option

Option 2)

[Co(H2O)6]3+, [Co(en)3]3+, [Co(NH3)6]3+

This is incorrect option

Option 3)

[Co(H2O)6]3+, [Co(NH3)6]3+, [Co(en)3]3+

This is incorrect option

Option 4)

[Co(NH3)6]3+, [Co(en)3]3+, [Co(H2O)6]3+

This is incorrect option
