To calculate the oxidation numbers for (CH3)COO(C2H5), count the number of atoms, draw the lewis structure by adding bonds, assign electrons from each bond, and count the number of electrons assigned to each atom. Count Atoms Use the chemical formula, (CH3)COO(C2H5), to count the number...
化学式CH3CH2C=OCH2COOH所表示的化合物是一种酮酸,称为戊二酸异丁酯。戊二酸异丁酯分子中含有一个含氧的羰基官能团和一个含氧的羧基官能团,这些官能团可以与Lewis酸发生配位作用。氯化铁FeCl3是一种Lewis酸,当将戊二酸异丁酯溶于氯化铁水溶液中,戊二酸异丁酯中的羰基和羧基都可以与氯化铁形成络合物。
