  2. Protic solvent - Wikipedia

    en.wikipedia.org/wiki/Protic_solvent

    In general terms, any solvent that contains a labile H + is called a protic solvent. The molecules of such solvents readily donate protons (H +) to solutes, often via hydrogen bonding. Water is the most common protic solvent. Conversely, polar aprotic solvents cannot donate protons but still have the ability to dissolve many salts. [1] [2]

  3. Solvent effects - Wikipedia

    en.wikipedia.org/wiki/Solvent_effects

    The following table shows the effect of solvent polarity on the relative reaction rates of the S N 2 reaction of 1-bromobutane with azide (N 3 –). There is a noticeable increase in reaction rate when changing from a protic solvent to an aprotic solvent. This difference arises from acid/base reactions between protic solvents (not aprotic ...

  4. Solvation - Wikipedia

    en.wikipedia.org/wiki/Solvation

    Polar solvents are often found to have a high dielectric constant, although other solvent scales are also used to classify solvent polarity. Polar solvents can be used to dissolve inorganic or ionic compounds such as salts. The conductivity of a solution depends on the solvation of its ions. Nonpolar solvents cannot solvate ions, and ions will ...

  5. Solvent - Wikipedia

    en.wikipedia.org/wiki/Solvent

    The following table shows that the intuitions from "non-polar", "polar aprotic" and "polar protic" are put numerically – the "polar" molecules have higher levels of δP and the protic solvents have higher levels of δH. Because numerical values are used, comparisons can be made rationally by comparing numbers.

  7. Inorganic nonaqueous solvent - Wikipedia

    en.wikipedia.org/wiki/Inorganic_nonaqueous_solvent

    An inorganic nonaqueous solvent is a solvent other than water, that is not an organic compound. These solvents are used in chemical research and industry for reactions that cannot occur in aqueous solutions or require a special environment. Inorganic nonaqueous solvents can be classified into two groups, protic solvents and aprotic solvents.

  8. SN1 reaction - Wikipedia

    en.wikipedia.org/wiki/SN1_reaction

    Typical polar protic solvents include water and alcohols, which will also act as nucleophiles, and the process is known as solvolysis. The Y scale correlates solvolysis reaction rates of any solvent (k) with that of a standard solvent (80% v/v ethanol/water) (k 0) through ⁡ =

  9. Hexafluoro-2-propanol - Wikipedia

    en.wikipedia.org/wiki/Hexafluoro-2-propanol

    As a solvent, hexafluoro-2-propanol is polar and exhibits strong hydrogen bonding properties. Testament to the strength of its hydrogen-bonding tendency is the fact that its 1:1 complex with THF distills near 100 °C. It has a relatively high dielectric constant of 16.7.
