Question

Number of resonating structure of ${\left(Si{O}_2\right)}_n$ is:

• A. $1$
• B. $2$
• C. $3$
• D. zero

Answer 1

The correct option is D zero

There are two resonating structures for $Si{O}_2$

But $(Si{O}_2{)}_n$ silica is a network structure having a never-ending array of atoms.

Thus there is zero resonating structure of $(Si{O}_2{)}_n$.
