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 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 =
