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.
Like other simple aliphatic amines, ethylamine is a weak base: the pK a of [CH 3 CH 2 NH 3] + has been determined to be 10.8 [8] [9]. Ethylamine undergoes the reactions anticipated for a primary alkyl amine, such as acylation and protonation.
Ortho effect is an organic chemistry phenomenon where the presence of a chemical group at the at ortho position or the 1 and 2 position of a phenyl ring, relative to the carboxylic compound changes the chemical properties of the compound.
See Amino acid for the pK a values of all amino acid side chains inferred in such a way. There are also numerous experimental studies that have yielded such values, for example by use of NMR spectroscopy. The table below lists the model pK a values that are often used in a protein pK a calculation, and contains a third column based on protein ...
Nitric acid, with a pK value of around −1.7, behaves as a strong acid in aqueous solutions with a pH greater than 1. [23] At lower pH values it behaves as a weak acid. pK a values for strong acids have been estimated by theoretical means. [24] For example, the pK a value of aqueous HCl has been estimated as −9.3.
−23.4 °C (−10.1 °F; 249.8 K) [3] Boiling point: 131.5 °C (268.7 °F; 404.6 K) [3] Solubility in water. 12 g/L (20 °C) [1] Solubility:
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.
