www.chem.latech.eduAmines with fewer than six carbon atoms are infinitely soluble in water. Solubility results from hydrogen bonding between the amines and water. Even tertiary amines are water-soluble because of its ability to form hydrogen bonds. Odor or smell Methylamines (mono-, di-, and tri-) and ethylamine (gases) have ammonia-like smell.
Ch 06 Amines and Amides - Angelo State University
www.angelo.edu• Amines in the IUPAC system: the “e” ending of the alkane name for the longest chain is replaced with –amine. The amine group is located by the position number. Groups that are attached to the nitrogen atom are located using “N” as the position number. More complex primary amines are named

Functional Groups - Purdue University
www.chem.purdue.eduG. Amines • contain an “amino” group – a N atom bonded to 1, 2, or 3 carbon atom groups by single bonds H. Aldehydes and Ketones • contain a C=O (“carbonyl”) group • note that in condensed structural formulas, the aldehyde group may be written as –CH=O or as –CHO I. Carboxylic Acids
TECHNIQUES: Principes de la chromatographie
zysman-colman.com6 11 Deux facteurs interviennent lors de l’interaction entre l’ éluant et le soluté (mélange de composés à séparer): • la solubilité: on doit être en mesure de dissoudre le soluté dans l’éluant pour que la migration se fasse. • la polarité de l’éluant va déterminer à quelle vitesse le composé migre. Moins un composé est polaire, moins il s’accroche à l ...
