Question

The hybridisation and geometry of $Br{F}_3$ molecules are:

• A. $s{p}^{3}d$ and $T-$shaped
• B. $s{p}^2{d}^2$ and tetragonal
• C. $s{p}^{3}d$ and bent
• D. none of these

Answer 1

The correct option is A $s{p}^{3}d$ and $T-$shaped

The geometry of bromine trifluoride is planar. It is a '$T-$shaped' molecule. Because it is not a trigonal planar due to the presence of lone two pairs of electrons on bromine. The fluorine atoms are repelled from the lone pairs causing it to have a unique shape. Bromine undergoes $s{p}^{3}d$ hybridization.

Hence option $A$ is correct.
