    en.wikipedia.org/wiki/Propylamine

    Propylamine, also known as n-propylamine, is an amine with the chemical formula CH 3 (CH 2) 2 NH 2. [1] It is a colorless volatile liquid. [2] Propylamine is a weak base. Its K b (base dissociation constant) is 4.7 × 10 −4.

  3. Propanamide - Wikipedia

    en.wikipedia.org/wiki/Propanamide

    Propanamide has the chemical formula CH 3 CH 2 C=O(NH 2). [1] It is the amide of propanoic acid. This organic compound is a mono-substituted amide. [2] Organic compounds of the amide group can react in many different organic processes to form other useful compounds for synthesis.

  4. Ethylamine - Wikipedia

    en.wikipedia.org/wiki/Ethylamine

    Ethylamine, also known as ethanamine, is an organic compound with the formula CH 3 CH 2 NH 2. This colourless gas has a strong ammonia-like odor. It condenses just below room temperature to a liquid miscible with virtually all solvents. It is a nucleophilic base, as is typical for amines. Ethylamine is widely used in chemical industry and ...

  5. n-Butylamine - Wikipedia

    en.wikipedia.org/wiki/N-Butylamine

    n-Butylamine is an organic compound (specifically, an amine) with the formula CH 3 (CH 2) 3 NH 2. This colourless liquid is one of the four isomeric amines of butane, the others being sec-butylamine, tert-butylamine, and isobutylamine. It is a liquid having the fishy, ammonia-like odor common to amines.

  6. Hexylamine - Wikipedia

    en.wikipedia.org/wiki/Hexylamine

    Hexylamine or n-hexylamine is a chemical compound with the formula CH 3 CH 2 CH 2 CH 2 CH 2 CH 2 NH 2. This colorless liquid is one of the isomeric amines of hexane. At standard temperature and pressure, it has the ammonia/bleach odor common to amines and is soluble in almost all organic solvents.

    From the titration of protonatable group, one can read the so-called pK a 1 ⁄ 2 which is equal to the pH value where the group is half-protonated (i.e. when 50% such groups would be protonated). The p K a 1 ⁄ 2 is equal to the Henderson–Hasselbalch p K a (p K HH

  8. Dipropylamine - Wikipedia

    en.wikipedia.org/wiki/Dipropylamine

    Dipropylamine is an organic compound with the formula (CH 3 CH 2 CH 2) 2 NH. It is classified as a secondary amine. It is a colorless liquid with a "fishy" odor. It is a precursor to various herbicides such as trifluralin, oryzalin, and vernolate. [3] Trifluralin, an herbicide containing a dipropylamino group

  9. Acid dissociation constant - Wikipedia

    en.wikipedia.org/wiki/Acid_dissociation_constant

    A simple example is provided by the effect of replacing the hydrogen atoms in acetic acid by the more electronegative chlorine atom. The electron-withdrawing effect of the substituent makes ionisation easier, so successive pK a values decrease in the series 4.7, 2.8, 1.4, and 0.7 when 0, 1, 2, or 3 chlorine atoms are present. [49]
