Number of lone pair

\left(s\right)

of electrons on central atom and the shape of

{BrF}_{3}

molecule respectively, are :
Number of lone pair (s) of electrons on central atom and the shape of BrF _ 3 molecule respectively, are :

Options

A $0$ , triangular planar.
B $1$ , pyramidal.
C $2$ , bent $T$ -shape.
D $1$ , bent $T$ -shape

Correct answer

C. $2$ , bent $T$ -shape.

Step-by-step solution

Number of lone pair (s) of electrons on central atom and the shape of BrF _ 3 molecule respectively, are :

Bromine undergo ${sp}^{3}d$ hybridization and the shape of the molecule is T-shape. Each fluorine is having $3$ lone pairs and bromine is having $2$ lone pairs. Hence, total $11$ lone pairs are there.
