Dear veluri
The structure of BrF5 is square pyramidal. The number of FBrF angles having the value of 90º is eight (8).
but Due to trivial distortion, however, the bond angles (F—Br—F) are slightly less than 90º(85º).
so this question has slight confusion.
Please feel free to post as many doubts on our discussion forum as you can.
