The hybridization of I3 (Triiodide ion) is sp3d. The way we draw the structure of molecular compounds on paper is just a two-dimensional form. The understanding of chemica… See more

If we take another look at the Lewis Structure of the ion I3-, we can easily see that the central iodine has three lone pairs. The lone pairs are positioned equatorially due to repu… See more

I3- is an interesting and difficult molecule to deal with when it comes to chemical bonding. Although the molecular geometry is linear as discussed earlier, the electronic geometry i… See more

Triiodide ion is a shining example of 3-center-4-electron chemical bonding. Now, what does it signify? Before that, a brief summary of MO or Molecular Orbital theory is placed b… See more
