Question

$S{i}_2{O}_7^{6-}$ anion is obtained when :

• A. no oxygen of a $Si{O}_4$ tetrahedron is shared with another $Si{O}_4$ tetrahedron
• B. one oxygen of a $Si{O}_4$ tetrahedron is shared with another $Si{O}_4$ tetrahedron
• C. two oxygen of a $Si{O}_4$ tetrahedron is shared with another $Si{O}_4$ tetrahedron
• D. three or all four oxygen of a $Si{O}_4$ tetrahedron is shared with another $Si{O}_4$ tetrahedron

Answer 1

The correct option is B one oxygen of a $Si{O}_4$ tetrahedron is shared with another $Si{O}_4$ tetrahedron

$S{i}_2{O}_7^{6-}$ anion is obtained when one oxygen of a $Si{O}_4$ tetrahedron is shared with another $Si{O}_4$ tetrahedron.
