  2. Iodine pentafluoride - Wikipedia

    en.wikipedia.org/wiki/Iodine_pentafluoride

    IF 5 reacts vigorously with water forming hydrofluoric acid and iodic acid: . IF 5 + 3 H 2 O → HIO 3 + 5 HF. Upon treatment with fluorine, it converts to iodine heptafluoride: [6]. IF 5 + F 2 → IF 7

  3. Chemical polarity - Wikipedia

    en.wikipedia.org/wiki/Chemical_polarity

    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

  4. Iodine heptafluoride - Wikipedia

    en.wikipedia.org/wiki/Iodine_heptafluoride

    Iodine heptafluoride is an interhalogen compound with the chemical formula I F 7. [2] [3] It has an unusual pentagonal bipyramidal structure, with D 5h symmetry, as predicted by VSEPR theory. [4]

  5. Trigonal bipyramidal molecular geometry - Wikipedia

    en.wikipedia.org/wiki/Trigonal_bipyramidal...

    In chemistry, a trigonal bipyramid formation is a molecular geometry with one atom at the center and 5 more atoms at the corners of a triangular bipyramid. [1] This is one geometry for which the bond angles surrounding the central atom are not identical (see also pentagonal bipyramid), because there is no geometrical arrangement with five terminal atoms in equivalent positions.

  6. Pentagonal planar molecular geometry - Wikipedia

    en.wikipedia.org/wiki/Pentagonal_planar...

    The only two pentagonal planar species known are the isoelectronic (nine valence electrons) ions [XeF 5] − (pentafluoroxenate(IV)) and [IF 5] 2− (pentafluoroiodate(III)). [1] ...

  7. Hydrophobe - Wikipedia

    en.wikipedia.org/wiki/Hydrophobe

    Hydrophobic molecules tend to be nonpolar and, thus, prefer other neutral molecules and nonpolar solvents. Because water molecules are polar, hydrophobes do not dissolve well among them. Hydrophobic molecules in water often cluster together, forming micelles. Water on hydrophobic surfaces will exhibit a high contact angle.

  8. Xenon difluoride - Wikipedia

    en.wikipedia.org/wiki/Xenon_difluoride

    Xenon difluoride is a linear molecule with an Xe–F bond length of 197.73 ± 0.15 pm in the vapor stage, and 200 pm in the solid phase. The packing arrangement in solid XeF

  9. Solvent effects - Wikipedia

    en.wikipedia.org/wiki/Solvent_effects

    This arises from the fact that polar solvents stabilize the formation of the carbocation intermediate to a greater extent than the non-polar-solvent conditions. This is apparent in the ΔE a, ΔΔG ‡ activation. On the right is an S N 2 reaction coordinate diagram. Note the decreased ΔG ‡ activation for the non-polar-solvent reaction ...
