Napalm Napalm Napalm is an incendiary mixture of a gelling agent and a volatile petrochemical (usually gasoline (petrol) or diesel fuel). The title is a portmanteau of the names of two of the constituents of the original thickening and gelling agents: co-precipitated aluminium salts of naphthenic and palmitic acids. Napalm B is the more modern version of napalm (utilizing styrene derivatives) and, although distinctly different in its chemical composition, is often referred to simply as "napalm". Napalm was originally developed in 1942 in a secret laboratory at Harvard University, by a team led by chemist Louis Fieser under the United States
Lewis acids and bases both Lewis acids and Lewis bases, because they can either accept a pair of electrons or donate a pair of electrons, depending upon the reaction. Lewis acids are diverse. Simplest are those that react directly with the Lewis base. But more common are those that undergo a reaction prior to forming the adduct. Again, the description of a Lewis acid is often used loosely. For example, in solution, bare protons do not exist. Some of the most studied examples of such Lewis acids are the boron trihalides and organoboranes, but other compounds exhibit this behavior: In this adduct, all four
