  2. Triiodide - Wikipedia

    en.wikipedia.org/wiki/Triiodide

    380.713 41 g·mol −1. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Infobox references. In chemistry, triiodide usually refers to the triiodide ion, I−. 3. This anion, one of the polyhalogen ions, is composed of three iodine atoms.

  3. Bond order - Wikipedia

    en.wikipedia.org/wiki/Bond_order

    The bond order itself is the number of electron pairs (covalent bonds) between two atoms. [2] For example, in diatomic nitrogen N≡N, the bond order between the two nitrogen atoms is 3 (triple bond). In acetylene H–C≡C–H, the bond order between the two carbon atoms is also 3, and the C–H bond order is 1 (single bond).

  4. Polyiodide - Wikipedia

    en.wikipedia.org/wiki/Polyiodide

    The polyiodides are a class of polyhalogen anions composed entirely of iodine atoms. [1] [2] The most common member is the triiodide ion, I −3.Other known larger polyiodides include [I 4] 2−, [I 5] −, [I 6] 2−, [I 7] −, [I 8] 2−, [I 9] −, [I 10] 2−, [I 10] 4−, [I 11] 3−, [I 12] 2−, [I 13] 3−, [I 14] 4-, [I 16] 2−, [I 22] 4−, [I 26] 3−, [I 26] 4−, [I 28] 4− and ...

  5. Order of precedence in Nepal - Wikipedia

    en.wikipedia.org/wiki/Order_of_precedence_in_Nepal

    The Order of precedence of Nepal is the protocol list (hierarchy) in which the functionaries and officials are listed according to their rank and office in the Government of Nepal. As the country embraces federalism, the government finalized a new order of precedence in April 2019. [ 1 ]

  6. Polyhalogen ions - Wikipedia

    en.wikipedia.org/wiki/Polyhalogen_ions

    Evidence supporting this theory comes from the bond lengths (255 pm in [ICl 2] − and 232 pm in ICl(g)) and bond stretching wavenumbers (267 and 222 cm −1 for symmetric and asymmetric stretching in [ICl 2] − compared with 384 cm −1 in ICl), which suggests a bond order of about 0.5 for each I–Cl bonds in [ICl 2] −, consistent with the ...

  8. Three-center four-electron bond - Wikipedia

    en.wikipedia.org/.../Three-center_four-electron_bond

    The 3-center 4-electron (3c–4e) bond is a model used to explain bonding in certain hypervalent molecules such as tetratomic and hexatomic interhalogen compounds, sulfur tetrafluoride, the xenon fluorides, and the bifluoride ion. [1][2] It is also known as the Pimentel–Rundle three-center model after the work published by George C. Pimentel ...

  9. Iodine–starch test - Wikipedia

    en.wikipedia.org/wiki/Iodine–starch_test

    Iodine–starch test. A bottle of iodine solution used on apples to determine the correct harvest time. The chart shows the level of residual starch. The cut surface of an apple stained with iodine, indicating a starch level of 4–5. The iodine–starch test is a chemical reaction that is used to test for the presence of starch or for iodine.
