(2005, 1M)
(a) $VOCl _2 ; FeCl _2$
(b) $CuCl _2 ; VOCl _2$
(c) $MnCl _2 ; FeCl _2$
(d) $FeCl _2 ; CuCl _2$
Show Answer
Solution:
- In $CuCl _2, Cu^{2+}$ has $d^{9}$ configuration, exhibit $d-d$ transition and show colour. Similarly in $VOCl _2, V^{4+}$ has $d^{1}$ configuration, can exhibit $d-d$ transition and show colour.
