Vedclass · Answer

(C) To determine if a coordination compound is coloured,we check for the presence of unpaired $d$-electrons. If the metal ion has a $d^0$ or $d^{10}$ configuration,it is typically colourless due to the absence of $d-d$ transitions.$1$. In $Ti(NO_3)_4$,$Ti$ is in the $+4$ oxidation state $(3d^0)$. It has no unpaired electrons,so it is colourless.$2$. In $[Cr(NH_3)_6]Cl_3$,$Cr$ is in the $+3$ oxidation state $(3d^3)$. It has unpaired electrons,so it is coloured.$3$. In $K_3[VF_6]$,$V$ is in the $+3$ oxidation state $(3d^2)$. It has unpaired electrons,so it should be coloured. Thus,the statement that it is colourless is incorrect.$4$. In $[Cu(NCCH_3)_4]BF_4$,$Cu$ is in the $+1$ oxidation state $(3d^{10})$. It has no unpaired electrons,so it is colourless.
