P Block Elements Question 396
$ ( SiO_2 )_{n}^{2n-} $ anion is obtained when:
Options:
A) no oxygen of a $ SiO_4^{4-} $ ’tetrahedron is shared with another $ SiO_4^{4-} $ tetrahedron
B) one oxygen of a $ SiO_4^{4-} $ tetrahedron is shared with another $ SiO_4^{4-} $ tetrahedron
C) two oxygen atoms of a $ SiO_4^{4-} $ tetrahedron are shared with another $ SiO_4^{4-} $ tetrahedron
D) three oxygen atoms of a $ SiO_4^{4-} $ tetrahedron are shared with another $ SiO_4^{4-} $ tetrahedron
Show Answer
Answer:
Correct Answer: D
Solution:
Total No. oxygen atoms per silicon atom $ =\frac{1}{2}+\frac{1}{2}+\frac{1}{2}+1=3.5 $ $ \therefore $ Formula $ Si_2O_5^{2-}. $
