Vedclass · Answer

(D) complex is colored if it contains a metal ion with an incomplete $d$-subshell,allowing for $d-d$ transitions.In $K_3[VF_6]$,the vanadium is in the $V^{3+}$ oxidation state.The electronic configuration of $V^{3+}$ is $[Ar] 3d^2$.Since it has unpaired electrons in the $d$-orbital,it undergoes $d-d$ transitions and exhibits color.In contrast,$Ti(NO_3)_4$ has $Ti^{4+}$ $(3d^0)$,$[Cu(NCCH_3)_4]^{+}$ has $Cu^{+}$ $(3d^{10})$,and $Li[AlH_4]$ contains $Al^{3+}$ $(2p^6)$,all of which lack unpaired $d$-electrons.
