Question

The structure of the $S{O}_3$ molecule in the gaseous phase contains:

• A. only $\sigma$-bonds between sulphur and oxygen
• B. $\sigma$-bonds and a (p$\pi$-p$\pi$) bonds between sulphur and oxygen
• C. $\sigma$-bonds and a (d$\pi$-p$\pi$) bonds between sulphur and oxygen
• D. $\sigma$-bonds, and a (p$\pi$-p$\pi$) and a (p$\pi$-d$\pi$) bonds between sulphur and oxygen

Answer 1

The correct option is D $\sigma$-bonds, and a (p$\pi$-p$\pi$) and a (p$\pi$-d$\pi$) bonds between sulphur and oxygen

There are $2$ double bonds and $1$ single bond.
