Shape of IF5

Postby Jacob Afable 3J » Sat Oct 24, 2015 5:24 pm

Could someone please explain to me why the shape of IF5 is square pyramidal?

The VSEPR formula for IF5 is AX5E, because there are six regions of electron density, but one corresponds to a lone pair, which is why the name is square pyramidal. Look at page 109 in the textbook, it has a picture there. Hope this helps!
