Conclusions

  1. 1.

    The molecules of 1-acetyl-, 1-trifluoroacetyl-, and 1-difluoroacetyl-1,2-dimethylhydrazines form hydrogen bonds, which remain in dilute solutions and, partly, in the gaseous state.

     
  2. 2.

    Associations in 1-acetyl-1,2-dimethylhydrazine are evidently realized with the participation both of the unshared electron pairs of the oxygen atom and of the nitrogen at position 2.

     
  3. 3.

    The introduction of fluorine atoms into the acyl fragment of the hydrazide molecule leads to the preferential formation of intermolecular hydrogen bonds of the N-H⋯N type.

     
  4. 4.

    The low probability of the formation of an intramolecular hydrogen bond of the N-H⋯ O=C type was demonstrated.
