Predict the shape of BrF_{5} .
STRATEGY
First, draw an electron-dot structure for BrF_{5} to determine that the central bromine atom has six charge clouds (five bonds and one lone pair). Then predict how the six charge clouds are arranged
Bromine pentafluoride
Six charge clouds implies an octahedral arrangement; five attached atoms and one lone pair BrF_{5} give a square pyramidal shape:
