The couple I c -I a is associated with reversible
formation of benzophenone ketyl 2 ( Eq. 2.8 ).
Peak II c should be associated with reduction of
2 to the reactive dianion 3 ( Eq. 2.9 ). In the
presence of phenol, 2 is protonated ( Eq. 2.10 ),
and the resulting radical 4 is then further
reduced to form the monoanion 5 ( Eq. 2.12 ).
Finally 5 is protonated to form the alcohol 6
( Eq. 2.13 ).
As we have seen in the above example, CV
provides preliminary information about the
mechanism of an unknown electrode reaction.
