GATE CY 2016 Question Paper (31-Jan-2016) (Shift 2)

The correct set of infra-red spectral bands (in $c{m}^{-1}$) for the ${\nu }_{CO}$ stretching mode of the given carbonyl complex is

The ${}^{19}F$ NMR spectrum of $Cl{F}_3$ when measured at $-60{}^{\circ }C$ will be observed as a

Among the given platinum(II) complexes, the one that is thermally the most unstable is

The shapes of $Xe{F}_5^{+}$ and $Xe{F}_5^{-}$, respectively, are

Sodium salts of pseudohalogens X, Y, and Z form colourless solutions in water. Solution of X decolorizes $I_3^{-}$ solution with brisk effervescence. Solution of Y gives an intense red colour on reaction with $F{e}^{3+}$ solution. Solution of Z gives an intense blue colour on reaction with a solution containing $F{e}^{3+}$ and $F{e}^{2+}$ ions. The pseudohalogens X, Y, and Z, respectively, are
