reactions of chloroalkanes, emphasizing inversion of configuration. However, if the carbon is not chiral (e.g., in some alkanes), no enantiomers are formed. Dicarboxylic Acids : Concepts related to fumaric acid and its reactions with cap B r sub 2 cap K cap M n cap O sub 4 were tested. For instance, reacting with alkaline cap K cap M n cap O sub 4 can result in the formation of cap C cap O sub 3 raised to the 2 minus power if the carbon chain is fully cleaved.
