Question

IF7 is polar or non-polar molecule?​

Answer 1

Answer:

pentagonal bipyramidal. This shape and the change in electronegativity makes the molecule non-polar

Answer 2

$IF_{7}$ is a non-polar molecule.

• In $IF_{7}$, iodine consists of seven valence electrons and all of them are occupied or bonded with seven electrons of the fluorine atoms.

• As iodine is a halogen with 7 electrons in the outermost shell which indicates that iodine is left with no electron and thus has no lone pair of electrons.
• A pentagonal bipyramidal shape is represented when there are zero lone pairs and seven bond pairs and when the iodine is $Sp^{3} d^{3}$ hybridized.
• The angle formed between the planar fluorine bonds and the axial bonds are 72° and 180° respectively.
• $IF_{7}$ have a very complex shape (pentagonal bipyramidal shape) and its dipole moment is either zero or close to it and thus, $IF_{7}$ is non-polar molecule.

Hence, $IF_{7}$ is a non-polar molecule.
