Phosphorus pentachloride, a key industrial compound with

Solution 85P:

Here, we are going to draw a Lewis structure, and name the molecular shape of each product of the following reaction.

Step 1:

The reaction between SO2 and PCl5 is given below:

Lewis structure is the representation of the bonding between atoms of a molecule and the lone pairs of electrons which exist in the molecule.

Lewis structure of POCl3:

Total valence electrons of POCl3 = (5 +6+37) =32 e-

Here, the P atom is surrounded by four electron groups around it. Therefore, its electron-group arrangement is tetrahedral with ideal angle 109.5o.

Thus, the molecular shape of POCl3 is tetrahedral.
