Question

The molecule which contains $s{p}^3{d}^2$ and p orbitals overlapping in it is:

• A. $PC{l}_5$
• B. $Br{F}_5$
• C. $Cl{F}_3$
• D. $I{F}_7$

Answer 1

The correct option is B $Br{F}_5$

The molecular geometry of $Br{F}_5$ is octahedral based on its electron pair geometry . The hybridization is $s{p}^3{d}^2$ wherein one s, three p and two d orbitals of bromine hybridize to form $s{p}^3{d}^2$ hybrid orbitals. These form a bond with p orbital of fluorine atoms.
