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.
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.
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 ...
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.
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
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
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]
