Question
Which of the following pairs are isostructural?
A.
$$SO_4^{2 - }\,{\text{and}}\,BF_4^ - $$
B.
$$N{H_3}\,{\text{and}}\,NH_4^ + $$
C.
$$CO_3^{2 - }\,{\text{and}}\,C{O_2}$$
D.
$$C{H_4}\,{\text{and}}\,B{F_3}$$
Answer :
$$SO_4^{2 - }\,{\text{and}}\,BF_4^ - $$
Solution :
$$SO_4^{2 - }$$ and $$BF_4^ - $$ have $$s{p^3}$$ hybridisation and are tetrahedral in shape.
