# What is the Lewis structure of sulfur dioxide? And what is /_O-S-O?

One........

#### Explanation:

We have $3 \times 6 = 18$ valence electrons to distribute around three centres; the least electronegative centre, $S$, is placed in the middle.

And we gets....$O = {\ddot{S}}^{+} - {O}^{-}$; and around each atom from left to right there are $6 , 5$, and $7$ $\text{valence electrons}$.........resulting in formal charges of $0 , + 1 , - 1$....

$\angle O - S - O = {119}^{\circ}$...................

Are the oxygens equivalent?
