Which of the following orders are correct ?

Answer»

`[FE(CO)_(4)]^(2-) lt [Co(CO)_(4)]^(-) lt [Ni(CO)_(4)] implies` STRETCHING vibrational frequency of C-O bond
`[Mn(Co)_(5)]^(-) lt [Mn(CO)_(6)]^(+) imples` EAN of central metal ion
`Trien=imda^(2-) implies " Denticity of ligand "`
`[Ni(en)_(3)]^(2+) lt [Ni(NH_(3))_(2)(en)_(2)]^(2+) implies` Number of STEREO isomers

Solution :(d) `[Ni(NH_(3))_(2)(en)_(2)]^(2+) implies "trans"`,cis (op. active)
