Hi, iam Wanda Baker, I hope you have the best day today.
Is Square Pyramidal Trigonal Bipyramidal? [Solved]
PCl5 has a trigonal bipyramidal shape, while IF5 has a square pyramidal shape. That’s because I has unshared electron pairs that are arranged to minimize repulsion, whereas PCl5 doesn’t have any non-bonding pairs. Plus, P’s octet is complete, but I’s isn’t.
