Question

Drew Lewis diagrams for the following compounds. In the formula the symbol of the central atom is given first. (Hint: The valence octet may be expanded for the central atom.)

(a) $P{F}_5$ (b) $S{F}_4$ (C)$Xe{O}_2{F}_2$

Short answer

Lewis structure of the following compounds:

(a) $P{F}_5$

(b) $S{F}_4$

(c) $Xe{0}_2{F}_2$

Step-by-step solution

Lewis structures

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

Lewis structure of (a)

(a) $P{F}_5$

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

Lewis structure of (b)

(b) $S{F}_4$

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)$Xe{0}_2{F}_2$

The image below depicts the structure of xenon dioxide difluoride. The valence electron of each fluorine is 7, oxygen is 6 and xenon is 8.
