  2. Azide - Wikipedia

    en.wikipedia.org/wiki/Azide

    In chemistry, azide (/ ˈ eɪ z aɪ d /, AY-zyd) is a linear, polyatomic anion with the formula N − 3 and structure − N=N + =N −.It is the conjugate base of hydrazoic acid HN 3. Organic azides are organic compounds with the formula RN 3, containing the azide functional group. [1]

  3. Organic azide - Wikipedia

    en.wikipedia.org/wiki/Organic_azide

    The azide functional group can be shown by two resonance structures. An organic azide is an organic compound that contains an azide (– N 3) functional group. [1] Because of the hazards associated with their use, few azides are used commercially although they exhibit interesting reactivity for researchers.

  4. 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

  5. Homoleptic azido compounds - Wikipedia

    en.wikipedia.org/wiki/Homoleptic_azido_compounds

    Popular synthetic routes to homoleptic azido compounds. There are several general routes and strategies employed when synthesizing homoleptic azido compounds. Salt metathesis between an azide salt like sodium azide or silver azide and the metal chloride is how a lot of the earlier azides were prepared. [7]

    They dissolve in nonpolar solvents. Both undergo polymerization. S 4 N 4 is also unstable with respect to the elements, but less so that the isostructural Se 4 N 4. Heating S 4 N 4 gives a polymer, and a variety of molecular sulfur nitride anions and cations are also known.

  7. Aqueous normal-phase chromatography - Wikipedia

    en.wikipedia.org/wiki/Aqueous_normal-phase...

    In normal-phase chromatography, the least polar compounds elute first and the most polar compounds elute last. The mobile phase consists of a nonpolar solvent such as hexane or heptane mixed with a slightly more polar solvent such as isopropanol, ethyl acetate or chloroform. Retention decreases as the amount of polar solvent in the mobile phase ...

  9. Allenes - Wikipedia

    en.wikipedia.org/wiki/Allenes

    Because of the symmetry, an unsubstituted allene has no net dipole moment, that is, it is a non-polar molecule. R and S configurations are determined by precedences of the groups attached to the axial section of the molecule when viewed along that axis.
