    • Abstract


      Hydrogen bond formation between N−H of acetanilide and π electrons of some arenes has been studied by infrared spectroscopy. In the mixtures of CCl4 and arenes new N−H bands appeared at lower frequencies in addition to the N−H band observed in pure CCl4. The lower frequency bands are assigned to the N−H bonded to π electrons of the arenes. Formation constants of these complexes have been determined with different arene concentrations. The frequency shifts of the N−H band and the formation constants were found to increase with increase in alkyl substitution in the benzene ring. The relative frequency shifts and logarithmic values of formation constants bear linear relationship with each other.
