  2. Hydrogen bond - Wikipedia

    The resonance assisted hydrogen bond ... conventional alcohol. [25] In the IR spectrum, hydrogen bonding shifts ... atom—can form only two bonds; (ammonia has the ...

  3. Ammonolysis - Wikipedia

    en.wikipedia.org/wiki/Ammonolysis

    This mechanism [7] is similar to the hydrolysis of esters, the ammonia attacks the electrophilic carbonyl carbon forming a tetrahedral intermediate. The reformation of the C-O double bond ejects the ester. The alkoxide deprotonates the ammonia forming an alcohol and amide as products. [8] Ammonolysis of esters

  4. Ammonia - Wikipedia

    en.wikipedia.org/wiki/Ammonia

    The hydrogen in ammonia is susceptible to replacement by a myriad substituents. Ammonia gas reacts with metallic sodium to give sodamide, NaNH 2. [38] With chlorine, monochloramine is formed. Pentavalent ammonia is known as λ 5-amine, nitrogen pentahydride decomposes spontaneously into trivalent ammonia (λ 3-amine) and hydrogen gas at normal ...

  5. Ammonium fluoride - Wikipedia

    en.wikipedia.org/wiki/Ammonium_fluoride

    Ammonium fluoride sublimes when heated—a property common among ammonium salts. In the sublimation, the salt decomposes to ammonia and hydrogen fluoride; the two gases can still recombine, i.e. the reaction is reversible: [NH 4]F ⇌ NH 3 + HF

  6. Haber process - Wikipedia

    en.wikipedia.org/wiki/Haber_process

    Fritz Haber, 1918. The Haber process, [1] also called the Haber–Bosch process, is the main industrial procedure for the production of ammonia. [2] [3] It converts atmospheric nitrogen (N 2) to ammonia (NH 3) by a reaction with hydrogen (H 2) using finely divided iron metal as a catalyst:

  7. Ester - Wikipedia

    en.wikipedia.org/wiki/Ester

    An ester of a carboxylic acid.R stands for any group (typically hydrogen or organyl) and R ′ stands for any organyl group.. In chemistry, an ester is a compound derived from an acid (organic or inorganic) in which the hydrogen atom (H) of at least one acidic hydroxyl group (−OH) of that acid is replaced by an organyl group (R ′). [1]

  8. Properties of water - Wikipedia

    en.wikipedia.org/wiki/Properties_of_water

    Model of hydrogen bonds (1) between molecules of water. A single water molecule can participate in a maximum of four hydrogen bonds because it can accept two bonds using the lone pairs on oxygen and donate two hydrogen atoms. Other molecules like hydrogen fluoride, ammonia, and methanol can also form hydrogen bonds.

  9. Condensation reaction - Wikipedia

    en.wikipedia.org/wiki/Condensation_reaction

    However other molecules can also be lost, such as ammonia, ethanol, acetic acid and hydrogen sulfide. [2] The addition of the two molecules typically proceeds in a step-wise fashion to the addition product, usually in equilibrium, and with loss of a water molecule (hence the name condensation). [3]
