The ring size and the number of linked tetrahedral present in $\left[\mathrm{Si}_{6} \mathrm{O}_{18}\right]^{12-}$ are, respectively

(a)6 and 6

(b)12 and 6

(c)12 and 12

(d)6 and 12

Answer

Answer (as printed): B

Explanation

The structure of $[\mathrm{Si_6O_{18}}]^{12-}$ is shown below. Hence, the number of linked tetrahedra = 6. The size of the ring = 12.
