which of the following is the correct lewis structure for the compound pbr₃? structure c structure a…

Brief Explanations:

To determine the correct Lewis - structure for $PBr_3$, first find the valence electrons of each atom. Phosphorus ($P$) has 5 valence electrons and bromine ($Br$) has 7 valence electrons. In $PBr_3$, there are a total of $5 + 3\times7=26$ valence electrons. Phosphorus is the central atom. It forms three single bonds with the three bromine atoms, using 6 electrons. Each bromine atom has 3 lone - pairs of electrons, and the phosphorus atom has 1 lone - pair of electrons. By comparing the electron - pair distribution and bonding in each given structure with the correct electron - count and bonding pattern for $PBr_3$, we can identify the correct structure.

Answer:

(Without seeing the actual structures A, B, C, D, we can't give a specific option. But the above is the general way to find the correct one.)
