If an EHC monograph is proposed for a chemical not on the priority list, the IPCS Secretariat consults with the cooperating organizations and all the Participating Institutions before embarking on the preparation of the monograph.

The paraffin chains are not actually straight lines, but zigzag ones as each carbon maintains tetrahedral bond angles. They can rotate freely about any bond, so they represent more a plate of spaghetti than a pile of rods. All the paraffins have about the same chemical properties. They do not react with any of the common reagents, which gave them the name "paraffin" from Latin , "slight" and , "affinity." They do react readily with free radicals, which displace the hydrogens, notably in the reaction of burning. They are colorless and odorless. They dissolve in organic (nonpolar) solvents, but not in water. The melting and boiling temperatures increase with the number of carbon atoms, and are lower for the more compact molecules that do not get entangled so easily. At room temperature, methane to butane are gases, pentane to nonadecane (19 carbons) liquids, and eicosane and above solids. Eicosane, with 20 carbons, is a soft gel at room temperature, typical of petroleum jelly. Cetane, or n-hexadecane, with 16 carbons, melts at just below room temperature and boils at 287.5°C. Examples of paraffins are easy to find in daily life: natural gas (methane), gasoline, kerosene, lubricating oils, petroleum jelly and wax.
Two carbon atoms can be joined by double or triple bonds, and this gives further prospects for molecules. Some important examples are shown at the left. A compound that contains double or triple bonds between carbons is called , while those with only single bonds are . Just as saturated compounds are called , those with double bonds are and those with triple bonds . Aliphatic compounds with multiple bonds between carbons are, in general, called . The most important are the alkene ethylene and the alkyne acetylene, which are important starting points for making other organic compounds because of the activity of the double bonds, which also make possible. The we see every day are an example. Ethylene polymerizes into a saturated compound called polyethylene, or PE. This is made in two forms, high-density HDPE and low-density LDPE. Propylene polymerizes to polypropylene, PP, which is stronger than PE. If one hydrogen is replaced by a chlorine to form ethylene chloride, more commonly called vinyl chloride, the result is the saturated polymer polyvinyl chloride, or PVC. If a benzene ring is used instead of chlorine, the result is polystyrene, PS. Plastic articles usually carry a recycling symbol indicating the polymer used by a number in a triangle, plus the symbols given above. HDPE is 2, PVC is 3, LDPE is 4, PP is 5 and PS is 6.

The Janssen Pharmaceutica Prize for Creativity in Organic Synthesis (formerly Dr Paul Janssen Prize for Creativity in Organic Synthesis) was established in 1986 on the occasion of the first Belgian Organic Synthesis Symposium (BOSS). The Prize is intended to honour Dr Paul Janssen, founder of Janssen Pharmaceutica.
The Prize is awarded on a biennial basis, on the occasion of the BOSS, to a chemist under the age of 50 who has made a significant contribution to the field of organic synthesis in the broadest sense.

Dr. Bugarin received his BS in chemistry, pharmacy, and biology from Universidad Autónoma de Zacatecas in 2003, his MS from UTEP in 2005, and his Ph.D. from Texas A&M University in 2011. His doctoral training under the direction of Dr. Brian T. Connell focused on asymmetric catalysis, including ligand, catalyst, and reaction design. He then spent one year as a postdoctoral associate with Professor Javier Read de Alaniz at UC Santa Barbara working on the mild aerobic oxidation of hydroxylamines and hydrazines. Dr. Bugarin joined the faculty at UT Arlington in Fall 2012. His research interests are in the development of new organic and organometallic reactions, or more specifically, the efficient construction of carbon–nitrogen bonds, redox economy, synergistic catalysis, and their application in total synthesis, materials, and bioactive molecules.

Inorganic chemistry is characterized by ionic reactions in water solution. If we dissolve silver nitrate in water, we get solvated Ag+ and NO3- ions in solution. Now if we add salt, Na+ and Cl- are added to the solution. It happens that if silver and chlorine ions meet, they form AgCl molecules that ionize very little and are insoluble in water because they clump together. The silver chloride precipitates until either silver or chlorine runs out. Similarly, if a gas is evolved a reaction will go to completion. Usually, however, we have an equilibrium between reactants and products with both present at the same time. Inorganic reactions also occur in the solid state, but the nature of these reactions is much less well-known.

Organic chemistry (and all other chemistry at that) is completely described by the quantum mechanics of nuclei and electrons interacting by electrostatic forces. The small contributions of the magnetic interactions of orbital currents and spin magnetic moments is of interest in spectroscopy, but of no consequence in chemistry. Charges of like sign repel one another, so electrons are repelled by electrons and nuclei are repelled by nuclei, but electrons and nuclei attract one another strongly and at large distances. The classical forces are F = z1z2(e2/r2), where F is the force in dynes, e the magnitude of the electronic charge (4.803 x 10-10) in esu, r the distance between the charges z1e and z2e. For electrons, z = -1.
