Lewis structure of the following compounds:

Step-by-step solution

Lewis structures 

Lewis structure is one of simple form of representing compounds or ions that vividly shows the bonding between atoms presents through lines. Lone pairs (if any) are also shown.

Lewis structure of (a)

(a) ${\mathrm{PF}}_5$

The image below depicts the structure of phosphorus pentafluoride. The valence electron of each fluorine is 7 and phosphorus is 5.

Lewis structure of (b)

(b) ${\mathrm{SF}}_4$

The image below depicts the structure of sulfur tetrafluoride. The valence electron of each fluorine is 7 and phosphorus is 6.

Lewis structure of (c)

(c)${\mathrm{XeO}}_2{\mathrm{F}}_2$
