Question

Which of the following species are planar?

• A. $I_3^{-},Xe{F}_2,Cl{F}_3$
• B. $H_{2}O,\overline{O}Cl,IC{l}_2^{+}$
• C. $Xe{F}_5^{-},Xe{F}_4,B{F}_3$
• D. All are correct

Answer 1

Answer: (D)

All are correct

In $I_3^{-}$ the central iodine involves a three-center four-electron bond with linear planar structure.

$Xe{F}_2$ is linear planar

$Cl{F}_3$ is T-shaped

$H_{2}O$ has bent or V-shape structure

$O^{-}Cl$ linear structure

$IC{l}_2^{+}$ linear

$Xe{F}_5^{-}$pentagonal planar

$Xe{F}_4$ square planar

$B{F}_3$ trigonal planar
