Incendiary device UN pilots used 70,000 gallons of napalm, with approximately 60,000 gallons of this thrown by US forces. Winston Churchill, among others, criticized American use of napalm in Korea, calling it "very cruel", as the US/UN forces, he said, were "splashing it all over the civilian population", "tortur[ing] great masses of people". The American official who took this statement declined to publicize it. During the Vietnam War, the U.S. Air Force developed the CBU-55, a cluster bomb incendiary fuelled by propane, a weapon that was used only once in warfare. Napalm however, became an intrinsic element of U.S. military action during
Lewis acids and bases highly localized. Typical Lewis bases are conventional amines such as ammonia and alkyl amines. Other common Lewis bases include pyridine and its derivatives. Some of the main classes of Lewis bases are The most common Lewis bases are anions. The strength of Lewis basicity correlates with the of the parent acid: acids with high 's give good Lewis bases. As usual, a weaker acid has a stronger conjugate base. The strength of Lewis bases have been evaluated for various Lewis acids, such as I, SbCl, and BF. Nearly all electron pair donors that form compounds by binding transition elements can
