  2. Reductions with samarium(II) iodide - Wikipedia

    en.wikipedia.org/wiki/Reductions_with_samarium...

    Samarium (II) iodide is a one-electron reductant, and typically effects reduction through a series of electron transfer and proton transfer (from protic solvent) steps. [ 4 ][ 3 ] Reducible functional groups include: α-Functionalized carbonyl compounds. Ketones and aldehydes. Carboxylic acids (under strongly acidic or basic conditions) Organic ...

  3. Samarium(II) iodide - Wikipedia

    en.wikipedia.org/wiki/Samarium(II)_iodide

    Samarium (II) iodide is an inorganic compound with the formula SmI 2. When employed as a solution for organic synthesis, it is known as Kagan 's reagent. SmI 2 is a green solid and forms a dark blue solution in THF. [1] It is a strong one-electron reducing agent that is used in organic synthesis.

  4. Dehydration reaction - Wikipedia

    en.wikipedia.org/wiki/Dehydration_reaction

    Alkenes can be made from alcohols by dehydration. This conversion, among others, is used in converting biomass to liquid fuels. [2] The conversion of ethanol to ethylene is a fundamental example: [3] [4] CH 3 CH 2 OH → H 2 C=CH 2 + H 2 O. The reaction is accelerated by acid catalysts such as sulfuric acid and certain zeolites.

  5. Mass concentration (chemistry) - Wikipedia

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

    Although there are examples to the contrary, it should be stressed that the commonly used "units" of % w/v are grams per millilitre (g/mL). 1% m/v solutions are sometimes thought of as being gram/100 mL but this detracts from the fact that % m/v is g/mL; 1 g of water has a volume of approximately 1 mL (at standard temperature and pressure) and ...

  6. Self-ionization of water - Wikipedia

    en.wikipedia.org/wiki/Self-ionization_of_water

    e. The self-ionization of water (also autoionization of water, autoprotolysis of water, autodissociation of water, or simply dissociation of water) is an ionization reaction in pure water or in an aqueous solution, in which a water molecule, H 2 O, deprotonates (loses the nucleus of one of its hydrogen atoms) to become a hydroxide ion, OH −.

  7. Reduction of nitro compounds - Wikipedia

    en.wikipedia.org/wiki/Reduction_of_nitro_compounds

    The reduction of nitroaromatics is conducted on an industrial scale. [1] Many methods exist, such as: Catalytic hydrogenation using: Raney nickel [2] or palladium-on-carbon, [3] [4] [5] platinum(IV) oxide, or Urushibara nickel. [6] Iron in acidic media. [7] [8] [9] Sodium hydrosulfite [10] Sodium sulfide (or hydrogen sulfide and base ...

  8. Ideal solution - Wikipedia

    en.wikipedia.org/wiki/Ideal_solution

    Ideal solution. An ideal solution or ideal mixture is a solution that exhibits thermodynamic properties analogous to those of a mixture of ideal gases. [1] The enthalpy of mixing is zero [2] as is the volume change on mixing by definition; the closer to zero the enthalpy of mixing is, the more "ideal" the behavior of the solution becomes.

  9. Stoichiometry - Wikipedia

    en.wikipedia.org/wiki/Stoichiometry

    There is a 1:1 molar ratio of NH 3 to NO 2 in the above balanced combustion reaction, so 5.871 mol of NO 2 will be formed. We will employ the ideal gas law to solve for the volume at 0 °C (273.15 K) and 1 atmosphere using the gas law constant of R = 0.08206 L·atm·K −1 ·mol −1:
