Studies of Hydrogen Bonding. Part XXXVI. Dipole Moments of Pyridines, Quinolines and Acridine, and of their Hydrogen-Bonded Complexes with Phenol
The dipole moments of eight pyridines, three quinolines and acridine, and of their hydrogen-bonded complexes with phenol have been determined in carbon tetrachloride solution at 20 deg C.The data points for the correlation of the dipole moments with the ability of the proton acceptors to associate with phenol and with their basicity, are separated into two groups.In one group the compounds possess a resultant of the group moments that reinforces, whereas in the other group the resultant opposes the molecular dipole moment.The vectorially calculated dipole moments of the hydrogen-bonded complexes were found to be smaller than the corresponding dipole moments obtained experimentally.
