  3. Cyclobutadiene - Wikipedia

    en.wikipedia.org/wiki/Cyclobutadiene

    The compound is the prototypical antiaromatic hydrocarbon with 4 pi electrons (or π electrons). It is the smallest [n]-annulene ([4]-annulene).Its rectangular structure is the result of a pseudo [3] - (or second order) Jahn–Teller effect, which distorts the molecule and lowers its symmetry, converting the triplet to a singlet ground state.

    1,4-Dioxin (also referred as dioxin or p-dioxin) is a heterocyclic, organic, non-aromatic [2] compound with the chemical formula C 4 H 4 O 2.There is an isomeric form of 1,4-dioxin, 1,2-dioxin (or o-dioxin). 1,2-Dioxin is very unstable due to its peroxide-like characteristics.

  6. Cyclodecapentaene - Wikipedia

    en.wikipedia.org/wiki/Cyclodecapentaene

    Aromaticity can be induced in compounds having a [10]annulene-type core if planarity is forcibly imposed by other substituents. Two methods to do so are known. One method is to formally replace two hydrogen atoms by a methylene bridge ( −CH 2 − ); this gives the planar bicyclic 1,6-methano­[10]annulene ( 5 ).

  7. Transmission medium - Wikipedia

    en.wikipedia.org/wiki/Transmission_medium

    Unguided transmission media are methods that allow the transmission of data without the use of physical means to define the path it takes. Examples of this include microwave , radio or infrared . Unguided media provide a means for transmitting electromagnetic waves but do not guide them; examples are propagation through air, vacuum and seawater.
