GATE CY 2011 Question Paper (13-Feb-2011) (Shift-2)

The crystal field stabilization energy (CFSE) value for $[Ti(H_{2}O{)}_6{]}^{3+}$ that has an absorption maximum at $492\text{ nm}$ is

For $E{t}_{2}AlX$ ($X=PP{h}_2^{-}$, $P{h}^{-}$, $C{l}^{-}$ and $H^{-}$), the tendency towards dimeric structure follows the order

In the isoelectronic series, $V{O}_4^{3-}$, $Cr{O}_4^{2-}$ and $Mn{O}_4^{-}$, all members have intense charge transfer (CT) transitions. The INCORRECT statement is

The increasing order of wavelength of absorption for the complex ions:

i) $[Cr(N{H}_3{)}_6{]}^{3+}$, ii) $[CrC{l}_6{]}^{3-}$, iii) $[Cr(O{H}_2{)}_6{]}^{3+}$, iv) $[Cr(CN{)}_6{]}^{3-}$, is

The total number of metal-metal bonds in $R{u}_3(CO{)}_{12}$ and $C{o}_4(CO{)}_{12}$, respectively, is
