Question

Why does a compound in the excited triplet state undergo intersystem crossing before returning to the ground state? Describe the difference between fluorescence and phosphorescence. Why does the formation of the diimide require temperatures in excess of 200 degree C? Identify the oxidation number of chromium in each of the following chemical species (a) Cr_2 O_7 (b) Cr_2 O_3 (c) CrSO_4 (d) Cr_2 S_3 In each of the following reactions, identify the oxidizing and reducing agents. (a) C_6 H_8 O_6 + 2H + 2 NO_2 rightarrow C_6 H_6 O_6 + 2 H_2 O + 2 NO (b) 2 KMnO_4 + 16 HCI rightarrow 2 MnCI_2 + 5 CI_2 + 8 H_2 O + 2 KCI Balance each of the following redox reactions using the half-reaction method.
