The shape of sulphate ion is:

A)  square planar

B)  trigonal

C)  trigonal planar

D)  tetrahedral

Correct Answer: D

Solution :

                Sulphate ion \[(SO_{4}^{2-})\] has tetrahedral geometry, as in it, S-atom undergoes \[s{{p}^{3}}-\]hybridisation. \[S=1{{s}^{2}},2{{s}^{2}}2{{p}^{6}},3{{s}^{2}}3{{p}^{4}}\] S in II excited state =
