Vedclass · Answer

(B) The colour of transition metal ion salts is due to $d-d$ transitions of unpaired electrons in the $d-$orbital. Metal ion salts having the same number of unpaired electrons in their $d-$orbitals exhibit similar colours in an aqueous medium.For $VOCl_2$,the metal ion is $V^{4+}$,which has the electronic configuration $[Ar] 3d^1$. It has $1$ unpaired electron.For $CuCl_2$,the metal ion is $Cu^{2+}$,which has the electronic configuration $[Ar] 3d^9$. It also has $1$ unpaired electron.Since both $V^{4+}$ and $Cu^{2+}$ have $1$ unpaired electron,they are expected to show similar colours.

Which pair of compounds is expected to show similar colour in aqueous medium?
