Hi,
Can anyone explain to me why IF5 is square pyrimidal and not trigonal bipyrimidal?
Can anyone explain to me why IF5 is square pyrimidal and not trigonal bipyrimidal?
The molecular shape of IF5 is square pyramidal.
IF5 is square pyramidal because it has five bonding pairs of electrons and one lone pair, giving it a total of six electron groups. This arrangement results in a square pyramidal shape to minimize repulsion between the electron pairs.
The bond angle of IF5 is 90 degrees between the axial bonds and 180 degrees between the equatorial bonds.
There is one lone pair on the central atom in IF5.
The bond lengths in IF5 are not all equal. The axial bonds are longer than the equatorial bonds due to increased repulsion from the lone pair on the central atom.
