Question

$Br{F}_3$ molecule is:

• A. planar trigonal
• B. tetrahedral
• C. T-shaped
• D. trigonal pyramidal

Answer 1

The correct option is C T-shaped

In $Br{F}_3$ molecule out of 7 valencies of bromine 3 are satisfied by fluorine. So there are 2 lone pairs of electron present around the bromine along with 3 bond pairs. So, $Br{F}_3$ shows $s{p}^{3}d$ hybridization.

Hence, it should show trigonal bipyramidal geometry but it shows T-shape because of 2 lone pairs of electrons.

Option C is correct.
