In the title compound, C11H13N3O, the phenyl ring is disordered over two sites, with occupancy factors in a 0.520 (17):0.480 (17) ratio. The dihedral angle between the ring planes of the major and minor components of the disordered ring is 12.9 (2)°. In the crystal, molecules are linked by N—HO hydrogen bonds, forming R22(8) ring motifs. C—HO, C—HN and C—Hπ interactions also occur.

In the title compound, C21H16F2O2, the central benzene ring is inclined at dihedral angles of 30.91 (8) and 46.88 (7)° to the two terminal fluoro-substituted rings. The dihedral angle between the two terminal fluoro-subsituted rings is 68.34 (8)°. An intramolecular C—HO hydrogen bond generates an S(6) ring motif. The crystal structure is stabilized by weak C—Hπ interactions.

In the title compound, C22H18F2O3, the two fluoro-substituted rings form dihedral angles of 25.89 (15) and 55.00 (12)° with the central benzene ring. The ethoxy group in the molecule is disordered over two positions with a site-occupancy ratio of 0.662 (7):0.338 (7). In the crystal, molecules are linked by C—HO hydrogen bonds into chains along the a axis. The crystal packing is further stabilized by C—Hπ and π—π interactions, with centroid–centroid distances of 3.8605 (15) Å.
