Webcis-Diamminedichloroplatinum II (cisplatin) is a potent anticancer chemotherapeutic agent. The major limitation in its use is nephrotoxicity, caused by an unknown mechanism. Injection of cisplatin into rats caused a decrease in body weight and an increase in blood urea nitrogen (BUN). These effects were modified by giving a radical scavenger, α-tocopherol, …

WebIntroduction Mass spectroscopy is one of the most generally applicable tools providing both qualitative and quantitative information about the atomic and molecular materials. WebIn some cases, homolytic fission can be achieved by supplying only a small amount of heat to the molecule. One such example is the homolytic cleavage of the oxygen-oxygen bonds in peroxides. These …

http://www.organicmystery.com/fission-of-cavalent-bond.php WebThe breaking of a chemical connection and the formation of two unequal fragments is known as heterolytic fission. It provides two bond electrons to one fragment and none to the other. The main distinction between homolytic and heterolytic fission is this. The "heterolytic bond dissociation energy" is the amount of energy absorbed or released ...

WebContinually formed + broke down by UV: 1 st O 2 → 2O, then steady state set up where rate formation is same as rate broken down O 2 + O ⇌ O 3 CFC’s remain stable until they reach the stratosphere. UV breaks carbon-halogen bond by homolytic fission to form radicals. Photodissociation: radiation initiating break down e.g. WebThe homolytic bond breaking can be defined as the breaking of bonds in equal halves. This type of bond cleavage is observed in the case of homonuclear diatomic molecules. Such bond- breaking results in the formation of the radical active species.
