  5. Ylide - Wikipedia

    en.wikipedia.org/wiki/Ylide

    An ylide (/ ˈ ɪ l aɪ d /) [1] or ylid (/ ˈ ɪ l ɪ d /) is a neutral dipolar molecule containing a formally negatively charged atom (usually a carbanion) directly attached to a heteroatom with a formal positive charge (usually nitrogen, phosphorus or sulfur), and in which both atoms have full octets of electrons.

  6. Ion-neutral complex - Wikipedia

    en.wikipedia.org/wiki/Ion-neutral_complex

    An ion-neutral complex in chemistry is an aggregate of an ion with one or more neutral molecules in which at least one of the partners has a rotational degree of freedom about an axis perpendicular to the intermolecular direction [1] In chemistry, the dissociation of a molecule into two or more fragments can take place in the gas phase, provided there is sufficient internal energy for the ...

  7. Zwitterion - Wikipedia

    en.wikipedia.org/wiki/Zwitterion

    In chemistry, a zwitterion (/ ˈ t s v ɪ t ə ˌ r aɪ ə n / TSVIT-ə-ry-ən; from German Zwitter 'hermaphrodite'), also called an inner salt or dipolar ion, [1] is a molecule that contains an equal number of positively and negatively charged functional groups. [2] 1,2-dipolar compounds, such as ylides, are sometimes excluded from the ...

  8. Neutralization (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Neutralization_(chemistry)

    In chemistry, neutralization or neutralisation (see spelling differences) is a chemical reaction in which acid and a base react with an equivalent quantity of each other. In a reaction in water, neutralization results in there being no excess of hydrogen or hydroxide ions present in the solution.
