  2. Sodium hydroxide - Wikipedia

    en.wikipedia.org/wiki/Sodium_hydroxide

    The only hydrates with stable melting points are NaOH·H 2 O (65.10 °C) and NaOH·3.5H 2 O (15.38 °C). The other hydrates, except the metastable ones NaOH·3H 2 O and NaOH·4H 2 O (β) can be crystallized from solutions of the proper composition, as listed above. However, solutions of NaOH can be easily supercooled by many degrees, which ...

  3. Ethanol - Wikipedia

    en.wikipedia.org/wiki/Ethanol

    Ethanol (also called ethyl alcohol, grain alcohol, drinking alcohol, or simply alcohol) is an organic compound with the chemical formula CH 3 CH 2 OH.It is an alcohol, with its formula also written as C 2 H 5 OH, C 2 H 6 O or EtOH, where Et stands for ethyl.

  4. Sodium hydrosulfide - Wikipedia

    en.wikipedia.org/wiki/Sodium_hydrosulfide

    This compound is the product of the half-neutralization of hydrogen sulfide (H 2 S) with sodium hydroxide (NaOH). NaSH and sodium sulfide are used industrially, often for similar purposes. Solid NaSH is colorless. The solid has an odor of H 2 S owing to hydrolysis by atmospheric moisture.

  5. Sodium ethoxide - Wikipedia

    en.wikipedia.org/wiki/Sodium_ethoxide

    In moist air, CH 3 CH 2 ONa hydrolyses rapidly to sodium hydroxide (NaOH). The conversion is not obvious and typical samples of CH 3 CH 2 ONa are contaminated with NaOH. In moisture -free air, solid sodium ethoxide can form sodium ethyl carbonate from fixation of carbon dioxide from the air.

  6. Chloroethane - Wikipedia

    en.wikipedia.org/wiki/Chloroethane

    Chloroethane is produced by hydrochlorination of ethylene: [11]. C 2 H 4 + HCl → C 2 H 5 Cl. At various times in the past, chloroethane has also been produced from ethanol and hydrochloric acid, from ethane and chlorine, or from ethanol and phosphorus trichloride, but these routes are no longer economical.

  7. Chromium(III) hydroxide - Wikipedia

    en.wikipedia.org/wiki/Chromium(III)_hydroxide

    Chromium(III) hydroxide is a gelatinous green inorganic compound with the chemical formula Cr(OH) 3.It is a polymer with an undefined structure and low solubility. It is amphoteric, dissolving in both strong alkalis and strong acids.

  8. 2-Chlorobutane - Wikipedia

    en.wikipedia.org/wiki/2-Chlorobutane

    2-Chlorobutane can be synthesized through the addition of hydrochloric acid to 2-butene in the following reaction: . The reaction is two-step, with the pi electrons attacking the chloride hydrogen, which forms a chloride nucleophile.

  9. 2-Naphthol - Wikipedia

    en.wikipedia.org/wiki/2-Naphthol

    2-Naphthol, or β-naphthol, is a fluorescent colorless (or occasionally yellow) crystalline solid with the formula C 10 H 7 OH. It is an isomer of 1-naphthol, differing by the location of the hydroxyl group on the naphthalene ring.
