Question

It is an experimental fact that Cs2[CuCl4]is orange coloured but (NH4)2[CuCl4] is yellow. It is further known that total paramagnetic moment of unpaired electron is due to spin as well as due to to nature of orbital,'d' orbital contributing more than 's' or 'p'.Thus, the total paramagnetic moment of orange is found to be more than that of yellow compound. Then, which of the following is correct
(A) Anion of Orange compound is tetrahedral and that of yellow is square planar.
(B) Anion of Orange compound is square planar and that of yellow is tetrahedral.
(C) Both the anions are tetrahedral
(D) Both the anions are square planar​

Answer 1

A) Anion of Orange compound is tetrahedral and that of yellow is square planar.

(B) Anion of Orange compound is square planar and that of yellow is tetrahedral.

(C) Both the anions are tetrahedral

(D) Both the anions are square planar
