Abstract
Certain reactions, such as acid catalysed hydration of unsaturated compounds, as examplified by the acetylenes: are considerably faster photochemically than thermally. This is assumed to be due to the enhanced basicity of the low-lying excited states over the electronic ground state basicity. Ab initio computations reconfirmed the validity of this assumption. The ground and excited state basicity of a number of unsaturated organic functional groups, with and without the inclusion of heteroatoms, will be discussed.
