# How do you draw the Lewis Structure for OPBr_3?

$\text{Of phosphoryl bromide?}$. There are $6 + 5 + 3 \times 7 = 32$ electrons to distribute.
Lewis structures of $O = P B {r}_{3}$ or ""^(-)O-^(+)PBr_3 are appropriate. The 2nd one is probably more common now. Each structure distributes 16 pairs of valence electrons as is required.
