Question

BrF₅ molecule is an interhalogen compound.

What is the structure of the given molecule?

विकल्प

• Pentagonal bipyramidal

• Square pyramidal

• square planar

• Tetrahedral

Answer 1

Square pyramidal

Explanation:

In BrF₅, bromine is the central atom with 7 valence electrons. It forms 5 bonds with fluorine atoms and has 1 lone pair. Total electron pairs = 6 ⇒ sp³d² hybridisation, which gives an octahedral electron geometry, but due to one lone pair, the molecular shape becomes square pyramidal.
