EBK A SMALL SCALE APPROACH TO ORGANIC L, Chapter 54, Problem 1Q , additional homework tip 1

The quantum yield for the given reaction is a unity which states that each molecule of excited benzophenone gives one molecule of benzo pinacol. In the given reaction; fluorescence is not observed, a triplet excited state is involved. n-Π* triplet excited state takes a hydrogen atom from isopropanol.

The mechanism of the given reaction is shown below:

Where,

S0 = singlet ground state

S1 = first singlet excited state

T1 = first triplet excited state

ISC = intersystem crossing

EBK A SMALL SCALE APPROACH TO ORGANIC L, Chapter 54, Problem 1Q , additional homework tip 3
