Abstract
Ketones in iodine solution are capable of transferring a nonbonding electron from the carbonyl oxygen to a halogen molecule forming a charge transfer complex. The electron-repelling nature of alkyl groups on either side of the carbonyl contributes to electron density and makes the ketone a better donor. The equilibrium constant of complex formation is an experimental measure of relative donor basicity and a theoretical measure of inductive effects. This study has determined that (1) the difference in inductive nature between a n-propyl and a methyl group is apparently negligible and (2) equilibrium constants may not be correlated with inductive effects when a substituent group interacts with the π-electrons of the carbonyl.
