  2. Acetate - Wikipedia

    en.wikipedia.org/wiki/Acetate

    An acetate is a salt formed by the combination of acetic acid with a base (e.g. alkaline, earthy, metallic, nonmetallic or radical base). "Acetate" also describes the conjugate base or ion (specifically, the negatively charged ion called an anion) typically found in aqueous solution and written with the chemical formula C 2 H 3 O − 2.

  3. Formal charge - Wikipedia

    en.wikipedia.org/wiki/Formal_charge

    Formal charges in ozone and the nitrate anion. In chemistry, a formal charge (F.C. or q*), in the covalent view of chemical bonding, is the hypothetical charge assigned to an atom in a molecule, assuming that electrons in all chemical bonds are shared equally between atoms, regardless of relative electronegativity.

  4. Charge number - Wikipedia

    en.wikipedia.org/wiki/Charge_number

    Using the chart provided, if ammonium with a plus 1 charge is combined with an acetate ion with a negative 1 charge, the charges will be cancelled out, shown in the figure below. NH 4 + + C 2 H 3 O 2 − NC 2 H 7 O 2 {\displaystyle {\ce {NH4+ + C2H3O2^- -> NC2H7O2}}}

  5. IUPAC nomenclature of inorganic chemistry 2005 - Wikipedia

    The μ 4 describes the bridging of the central oxide ion. (Note the use of the kappa convention to describe the bridging of the acetate ion where both oxygen atoms are involved.) In the name where a ligand is involved in different modes of bridging, the multiple bridging is listed in decreasing order of complexity, e.g. μ 3 bridging before μ ...

  6. Electron counting - Wikipedia

    en.wikipedia.org/wiki/Electron_counting

    ionic counting: Fe(0) contributes 8 electrons, each CO contributes 2 each: 8 + 2 × 5 = 18 valence electrons conclusions: this is a special case, where ionic counting is the same as neutral counting, all fragments being neutral. Since this is an 18-electron complex, it is expected to be isolable compound. Ferrocene, (C 5 H 5) 2 Fe, for the ...

  7. Pauling's principle of electroneutrality - Wikipedia

    en.wikipedia.org/wiki/Pauling's_principle_of...

    There are two possible structures for hydrogen cyanide, HCN and CNH, differing only as to the position of the hydrogen atom. The structure with hydrogen attached to nitrogen, CNH, leads to formal charges of -1 on carbon and +1 on nitrogen, which would be partially compensated for by the electronegativity of nitrogen and Pauling calculated the net charges on H, N and C as -0.79, +0.75 and +0.04 ...

  8. Ate complex - Wikipedia

    en.wikipedia.org/wiki/Ate_complex

    A lyate ion is a generic solvent molecule that has become a negative ion by loss of one or more protons. The -ate suffix also applies to negative fluoroanions, fluorides which have gained one or more protons and twice as many electrons. Tetrafluoroborate, BF − 4, is boron trifluoride, BF 3, which has gained one fluoride and two electrons.

  9. Acyl group - Wikipedia

    en.wikipedia.org/wiki/Acyl_group

    The carbon centres of acylium ions generally have a linear geometry and sp atomic hybridization, and are best represented by a resonance structure bearing a formal positive charge on the oxygen (rather than carbon): [R−C≡O +]. They are characteristic fragments observed in EI-mass spectra of ketones.
