    en.wikipedia.org/wiki/Formaldehyde

    Molecular formaldehyde. A colorless gas with a characteristic pungent, irritating odor. It is stable at about 150 °C, but it polymerizes when condensed to a liquid. 1,3,5-Trioxane, with the formula (CH 2 O) 3. It is a white solid that dissolves without degradation in organic solvents. It is a trimer of molecular formaldehyde.

    Glucose (C 6 H 12 O 6), ribose (C 5 H 10 O 5), Acetic acid (C 2 H 4 O 2), and formaldehyde (CH 2 O) all have different molecular formulas but the same empirical formula: CH 2 O.This is the actual molecular formula for formaldehyde, but acetic acid has double the number of atoms, ribose has five times the number of atoms, and glucose has six times the number of atoms.

    Sometimes a chemical formula is complicated by being written as a condensed formula (or condensed molecular formula, occasionally called a "semi-structural formula"), which conveys additional information about the particular ways in which the atoms are chemically bonded together, either in covalent bonds, ionic bonds, or various combinations of ...

  6. Chemical polarity - Wikipedia

    en.wikipedia.org/wiki/Chemical_polarity

    As a quantum-mechanical description, Pauling proposed that the wave function for a polar molecule AB is a linear combination of wave functions for covalent and ionic molecules: ψ = aψ(A:B) + bψ(A + B −). The amount of covalent and ionic character depends on the values of the squared coefficients a 2 and b 2. [4]

    Ionic compounds without these ions are also known as salts and can be formed by acid–base reactions. Ionic compounds can also be produced from their constituent ions by evaporation of their solvent , precipitation , freezing , a solid-state reaction , or the electron transfer reaction of reactive metals with reactive non-metals, such as ...
