The actual bond angles would be slightly less than 90 o Meanwhile in XY4 system although the molecular graphs show bond critical points (BCP) for X⋯Y, the dihalogen bond distance values are much longer than sum of the tabulated van der Waals radii for X and Y. Octahedral. Shape (or molecular structure) refers to the position of the atoms in a molecule. Transcript: This is the ICl5 Lewis structure. You can follow their steps in the video explanation above. What is the molecular geometry of ICl5? According to VSEPR, molecules will have a geometric shape that allows their negative charge centers (bonded and lone pair electrons) to be as far away from each other as possible, due to the mutual repulsion of the negative charges. What is the molecular geometry (shape) of I3â? Additionally, the type of hybrid orbitals should be determined. Therefore repultion items-12÷2=6.
