The following exergonic equilibrium gives rise to the triiodide ion: . I 2 + I − ⇌ I − 3. In this reaction, iodide is viewed as a Lewis base, and the iodine is a Lewis acid.The process is analogous to the reaction of S 8 with sodium sulfide (which forms polysulfides) except that the higher polyiodides have branched structures.
Hydrolysis occurs only slowly in water forming arsenic trioxide and hydroiodic acid.The reaction proceeds via formation of arsenous acid which exists in equilibrium with hydroiodic acid.
When comparing a polar and nonpolar molecule with similar molar masses, the polar molecule in general has a higher boiling point, because the dipole–dipole interaction between polar molecules results in stronger intermolecular attractions. One common form of polar interaction is the hydrogen bond, which is also
Finally, the triiodide ion (I − 3) is also based upon a trigonal bipyramid, but the actual molecular geometry is linear with terminal iodine atoms in the two axial positions only and the three equatorial positions occupied by lone pairs of electrons (AX 2 E 3); another example of this geometry is provided by xenon difluoride, XeF 2.

Elton John's gift may be his song, but that doesn't mean he loves them all.. During an appearance on The Late Show with Stephen Colbert on Tuesday, Dec. 17, the 77-year-old musician spoke about ...
Phosphorus triiodide (PI 3) is an inorganic compound with the formula PI 3. A red solid, it is too unstable to be stored for long periods of time; it is, nevertheless, commercially available. [ 2 ] It is widely used in organic chemistry for converting alcohols to alkyl iodides and also serves as a powerful reducing agent.
