Question

The structure of $Cl{F}_3$ is:

• A. Trigonal planar
• B. T-shaped
• C. Pyramidal
• D. Bent shaped

Answer 1

The correct option is B T-shaped

In $Cl{F}_3$ the central atom $Cl$ has three sigma bond and two lone pairs of electrons. Thus, the steric number is $5$.
Hence, $Cl$ in $Cl{F}_3$ is $s{p}^{3}d$ hybridised.
According to Bent's rule in case of $s{p}^{3}d$ hybridisation, more electronegative species are present at the axial bond.
So, the structure of $Cl{F}_3$ is as follows.


The shape of $Cl{F}_3$ is T-shaped.
