Bromine pentafluoride, BrF5, is sometimes used as a rocket propellant. Clearly one would like to know quite a bit about the chemical nature of this compound in order to predict how it might behave when loaded into a rocket.

Answer:

BrF5: 5 bonds and 1 lone pair

a) electron geometry: octahedral ; AB6
b) square pyramidal; AB5E
c) Ignor the effects of lone pair; it would be 90 degree
d). add up bonds and lone pair; sp3d2
e). The bonds are polar Br-F; and the molecule overall is polar:dipole moment.
