  2. Sulfonic acid - Wikipedia

    en.wikipedia.org/wiki/Sulfonic_acid

    General structure of a sulfonic acid with the functional group indicated in blue. In organic chemistry, sulfonic acid (or sulphonic acid) refers to a member of the class of organosulfur compounds with the general formula R−S(=O) 2 −OH, where R is an organic alkyl or aryl group and the S(=O) 2 (OH) group a sulfonyl hydroxide.

  3. 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

  4. Sulfate - Wikipedia

    en.wikipedia.org/wiki/Sulfate

    1 with polar covalent bonds only; 2 with an ionic bond Six resonances. The first description of the bonding in modern terms was by Gilbert Lewis in his groundbreaking paper of 1916 where he described the bonding in terms of electron octets around each atom, that is no double bonds and a formal charge of +2 on the sulfur atom and -1 on each ...

  5. Polar aprotic solvent - Wikipedia

    en.wikipedia.org/wiki/Polar_aprotic_solvent

    A polar aprotic solvent is a solvent that lacks an acidic proton and is polar. Such solvents lack hydroxyl and amine groups. In contrast to protic solvents, these solvents do not serve as proton donors in hydrogen bonding, although they can be proton acceptors. Many solvents, including chlorocarbons and hydrocarbons, are classifiable as aprotic ...

  6. Sulfur monoxide - Wikipedia

    en.wikipedia.org/wiki/Sulfur_monoxide

    The SO molecule has a triplet ground state similar to O 2 and S 2, that is, each molecule has two unpaired electrons. [2] The S−O bond length of 148.1 pm is similar to that found in lower sulfur oxides (e.g. S 8 O, S−O = 148 pm) but is longer than the S−O bond in gaseous S 2 O (146 pm), SO 2 (143.1 pm) and SO 3 (142 pm).

  7. Sulfite sulfate - Wikipedia

    en.wikipedia.org/wiki/Sulfite_sulfate

    A sulfite sulfate is a chemical compound that contains both sulfite and sulfate anions [SO 3] 2− [SO 4] 2−.These compounds were discovered in the 1980s as calcium and rare earth element salts.

  8. Gallium(III) sulfate - Wikipedia

    en.wikipedia.org/wiki/Gallium(III)_sulfate

    Gallium(III) sulfate refers to the chemical compound, a salt, with the formula Ga 2 (SO 4) 3, or its hydrates Ga 2 (SO 4) 3 ·xH 2 O. Gallium metal dissolves in sulfuric acid to form solutions containing [Ga(OH 2) 6] 3+ and SO 4 2− ions.

  9. Hydrophobe - Wikipedia

    en.wikipedia.org/wiki/Hydrophobe

    Hydrophobic molecules tend to be nonpolar and, thus, prefer other neutral molecules and nonpolar solvents. Because water molecules are polar, hydrophobes do not dissolve well among them. Hydrophobic molecules in water often cluster together, forming micelles. Water on hydrophobic surfaces will exhibit a high contact angle.
