Pyridine is a basic heterocyclic organic compound with the chemical formula C 5 H 5 N. It is structurally related to benzene, with one methine group (=CH−) replaced by a nitrogen atom (=N−). It is a highly flammable, weakly alkaline, water-miscible liquid with a distinctive, unpleasant fish
Glycine (symbol Gly or G; [6] / ˈ ɡ l aɪ s iː n / ⓘ) [7] is an amino acid that has a single hydrogen atom as its side chain. It is the simplest stable amino acid ( carbamic acid is unstable). Glycine is one of the proteinogenic amino acids .
The following compounds are liquid at room temperature and are completely miscible with water; ... pyridine: 110-86-1 C 4 H 8 O 2 S: sulfolane: 126-33-0 (CH 2) 4 O ...

A polar molecule has a net dipole as a result of the opposing charges (i.e. having partial positive and partial negative charges) from polar bonds arranged asymmetrically. Water (H 2 O) is an example of a polar molecule since it has a slight positive charge on one side and a slight negative charge on the other. The dipoles do not cancel out ...
[1] [2] The word hydrophobic literally means "water-fearing", and it describes the segregation of water and nonpolar substances, which maximizes the entropy of water and minimizes the area of contact between water and nonpolar molecules. In terms of thermodynamics, the hydrophobic effect is the free energy change of water surrounding a solute. [3]
For example, sugar dissolves in water because both share the hydroxyl functional group (−OH) and hydroxyls interact strongly with each other. Plus, when functional groups are more electronegative than atoms they attach to, the functional groups will become polar, and the otherwise nonpolar molecules containing these functional groups become ...
Other common Lewis bases include pyridine and its derivatives. Some of the main classes of Lewis bases are amines of the formula NH 3−x R x where R = alkyl or aryl. Related to these are pyridine and its derivatives. phosphines of the formula PR 3−x Ar x. compounds of O, S, Se and Te in oxidation state −2, including water, ethers, ketones
