Question

Which of the statements is correct about $S{O}_2$?

• A. It contains two $\sigma$, two $\pi$ bonds and no lone pair of electrons
• B. It contains two $\sigma$ and one $\pi$ bond
• C. It contains two $\sigma$, two $\pi$ bonds and one lone pair of electrons
• D. None of the above

Answer 1

The correct option is C It contains two $\sigma$, two $\pi$ bonds and one lone pair of electrons

The sulphur dioxide molecule contains $2\sigma ,2\pi$ bonds and one lone pair of electrons. $S$ atom contains $6$ valence electrons out of which it shares $2$ electrons with $2$ $O$ atoms to form $2$ sigma bonds. It also shares $2$ electrons with $2$ $O$ atoms to form $\pi$ bonds. The remaining $2$ electrons appear as lone pair of electrons. $S{O}_2$ molecule has bent geometry. The $S$ atom undergoes $s{p}^2$ hybridization.
