Question

In which of the following molecules all $A-X$ bond lengths are identical?
[A = central atom and X = surrounding atom]

• A. $Xe{F}_4$
• B. $P{F}_5$
• C. Both (a) and (b)
• D. $S{F}_4$

Answer 1

The correct option is A $Xe{F}_4$

$Xe{F}_4$ undergoes $s{p}^3$ hybridization with 4 bond pairs and 2 lone pairs. 4 bond pairs lie in a plane. Thus, it has all the four $Xe-F$ bonds of equal length.
